Version 6.4 History

SSI Web 6.4.2 (20 Dec 2007)
The following bug fixes have been made to SSI Web:
  1. ACA/Web users who have used the advanced options to skip the Importances section or customize their Importances should read this important bug notice. These bugs have been fixed.
  2. Bug #2 in the bug notice also exists with paper-and-pencil CVA data. Utility estimation will be incorrect if there are decimals in the imported task responses and the analysis is done on a computer with regional settings specifying a decimal place other than '.' (period). This has been fixed.
  3. A "file not found" error sometimes occurs when testing the survey or preparing for web upload. This has been fixed.
SSI Web 6.4.0 (4 Dec 2007)

CVA/Web and CVA/HB are now available in the SSI Web platform. For information on CVA/Web, including purchase information, please visit the CVA/Web product page on our website.

The following enhancements have been made to SSI Web:
  1. Pasting bulleted lists from Microsoft Word will now remove the bullet points and tabs automatically.
The following changes have been made to SSI Web:
  1. Version 6.2 changed the Quota Control behavior such that respondents who restarted a survey after their quota had filled were restarted from the beginning of the survey and all of their previous data was lost. We have changed this behavior in this version. Now if a respondent abandons a survey and returns to take the survey (restarts), if the respondent belongs to a quota that is now filled, the respondent will be immediately skipped to the Disqualify Question associated with that quota (the question specified on the Settings tab).
The following bug fixes have been made to SSI Web:
  1. When attempting to convert an SSI Web study to version 6.2, an "Object Required" error would be shown if the study were configured to use UserNames and/or Passwords and it did NOT have a Password question. This has been fixed.
  2. When using large passwords sets, the size of the passwords file may grow significantly each time the Questionnaire Access Settings dialog is closed or when the "Prepare for Web Upload" operation is executed. The error "Too many fields defined" may have been shown. This has been fixed.

Version 6.2 History

SSI Web 6.2.0 (12 Sep 2007)
The following enhancements have been made to SSI Web:
  1. Passwords
    1. Improved interface for managing passwords.
    2. Up to 125 password fields (variables) may be used (before, just two passwords could be used, named UserName and Password). You may name password variables anything you choose following SSI Web question naming conventions.
    3. Each password field can be up to 255 characters in length, using numbers, letters, or even some symbols (before, the limitation was 12 alpha-numeric characters for UserName and 8 alpha-numeric characters for Password).
    4. Up to 248 additional "merged" data fields representing information you may know about respondents prior to asking this survey may be imported and are automatically merged into each respondent's data when the respondent accesses the survey. These data fields may be used during the questionnaire, such as to show the respondent's prior data, in skip patterns, etc. Because they are part of the final data set, these merged data fields may be used in Export.
    5. You may use cookies (instead of respondent passwords) to prohibit respondents from taking the survey multiple times and also to allow respondents to restart. (Of course, if respondents have set their browser to block cookies, they may complete the survey multiple times, and they cannot restart their surveys.)
    6. A new option is available to let respondents specify their own passwords. If they terminate the survey early, they can restart where they left off by retyping their customized password.
    7. Only a single password file (STUDYNAME.pwds) is created (rather than potentially many, under the old .p001, .p002, etc. naming convention). The .pwds file is saved in a Microsoft Jet Database format (Jet databases can be modified using Microsoft Access and can be accessed from Microsoft Office applications).
    8. Previously, if importing a very large number of passwords from a text file, it could take a long time to complete the operation. The new importer is much faster.
  2. Quota Control - Quota control now allows you to set multiple independent quotas. To illustrate this idea, consider quotas involving gender (male/female) and age (young/old). In the previous version of SSI Web, the quota might be established with 4 "buckets" (Male&Young=50, Male&Old=50, Female&Young=50, Female&Old=50). This example defines the composition of 200 respondents to be collected, each bucket defined by the intersection of gender and age. With v6.2, you have another option: setting two independent quota settings and check points, one for gender and one for age. The quota rules for gender might be: (Male=100, Female=100) and the rules for age might be: (Young=100, Old=100). Notice with this approach that we aren't concerned about how many young males, etc. we interview. Each variable is considered independently--we are just interested ("on the margin") in how many male vs. female, old vs. young we interview.
  3. One-Click Respondent Access - We have changed the "One-Click" respondent access (bypass page 1) method. The syntax used for the URL to bypass page 1 has been improved, making it compatible with more systems. We have also simplified the way that variables are "passed into" the survey, having you specify the variable names in a table (as part of the new passwords dialog) rather than asking you to set up individual questions on the first page to capture these passed-in variables. See One-Click Access for more information.
  4. Admin Module - The admin module has been updated, with an improved look and easier navigation. We've also provided an advanced feature for custom logins that define which menu items are available within the admin module.
The following features have been added to SSI Web:
  1. Users can now right-click a question in the Write Questionnaire dialog, revealing a menu that lets them rename the current question (or other actions). This saves the user a few clicks.
  2. Response option labels in select-type questions are now clickable (rather than requiring just that the radio-button or check box be clicked).
  3. A new Excel file format (.xml) export option permits more than 256 columns (Excel 2007 required).
  4. Explore Study Folder icon on the toolbar automatically opens the study folder in Windows Explorer. This is a convenient time-saver.
  5. Respondent's IP Address and Browser/OS information is now exportable. Collecting this information may also be turned off if there are privacy concerns (see the new Privacy tab on the Global Settings dialog).
  6. New System Functions: Browser( ), OperatingSystem( ), UserAgent( ), IPAddress( ), EncodeForURL( ).
The following changes have been made to SSI Web:
  1. In MaxDiff Scores Analysis, the 0-100 probability rescaling procedure has been modified. Previously, the scaling was more extreme and reflected the assumption that the respondent is choosing 1 of t items in a set, where t is the total number of items in the study. With this latest version, we now rescale to 0-100 assuming a scale factor consistent with respondents picking 1 of c items, where c is the number of items in each choice set.
The following bug fixes have been made to SSI Web:
  1. When creating a free format variable of type checkbox, and selecting the option to force the respondent to check a certain number of checkboxes within a specified range, the dialog was requiring the survey author to make the max checks GREATER than or equal to the number of response options. It should have required the survey author to make the max checks LESS than or equal to the number of response options. This bug was introduced in version 6.0.0 when these fields started accepting SSI Script. It has been fixed. (Note that a workaround was to wrap the number in SSI Script, e.g. setting Max Checks to [%5%].)
  2. ACA Calibration Concepts may show fewer attributes than the user defined for the "Number of Attributes in Each Concept" if prohibitions are in place. If this happens, ACA OLS and ACA HB analysis (HB only with the option turned on to calibrate utilities) would report an inconsistency. This bug was introduced in version 6.0.0 and has now been fixed.
  3. SPSS Export bug fixes:
    1. When a Checkbox variable of a Free Format question has more than 9 items and the data are exported as "Item Numbers" instead of "Checked / Unchecked", then an error would appear during export warning that the numeric value found is too wide. This has been fixed.
    2. The Write format for variables in SPSS data files created by SSI Web were always set to floating point (F8.2). The Write format is used when exporting to text files from SPSS. The floating point setting could cause formatting problems. The bug has been fixed.
    3. When exporting free format check box variables to SPSS as "Item Numbers" the missing value was being recorded for check boxes that were seen and were not checked. This bug has been fixed and now a zero is being recorded.

Version 6.0 History

SSI Web 6.0.6 (24 Apr 2007)
The following bug fixes have been made to SSI Web:
  1. Within ACA if "Randomize Attribute Order in Rating and Importance Questions" was checked and if a respondent restarted the survey within the ACARAT or ACAIMP sections then some ACARAT or ACAIMP questions may be skipped and not seen by the respondent. This bug was introduced in version 6.0.0 and has been fixed.
  2. If a respondent finished a survey, hit the back button in the browser, and then tried to submit a page from the survey, instead of seeing "Your survey has already been submitted. Thank you.", the browser would hang and no response from the web server would be seen. This act would then cause problems in the Online Administrative Module. The Online Administrative Module would hang when trying to Get Data, view the Study Summary, etc. This bug has been fixed.
  3. The CBC designer was modified slightly. In obscure cases, designs generated in this version may not match prior versions. Specifically, shortcuts to the complete enumeration / balanced overlap for ADM designs were enabled (previously inadvertently disabled).
  4. In CBC if you were using any of the following:
    • An Alternative - Specific CBC Design and Shelf Facing Display
    • Customized CBC questions (using Free Format) and "Align Common Attributes on Same Row" unchecked
    Then during the interview when the software should have been displaying nothing for a level, the first level of the first attribute was being shown. This bug has been fixed.
  5. SPSS export of multi-select (checkbox) data was not being saved correctly. When exporting a Select or Grid question to SPSS using "Item Numbers", checkboxes that were seen but not checked were being recorded as the "missing value", when they should have been recorded as a "0". This bug has been fixed.
  6. SPSS export of multi-select (checkbox) data was not being labeled correctly. When exporting a Grid question to SPSS using "Item Numbers", not all of the value labels were being added to each variable, and the value labels were incorrect. This bug has been fixed.
SSI Web 6.0.4 (3 Apr 2007)
The following bug fixes have been made to SSI Web:
  1. For CBC Alternative Specific designs using Complete Enumeration, concepts with only one attribute (constant alternatives) now are given the same chance of being included in the task as all the other possible concepts. Previously they were included before any non-constant alternative tasks.
  2. For CBC Alternative Specific designs that used Complete Enumeration, and had non-alternative specific prohibitions, a level may not have been shown even if a level could have been shown. Now, if a level is available, a level will always be shown.
  3. Balance was fixed in MaxDiff pair-wise designs when prohibitions are present.
  4. When saving the results of MaxDiff Counts, MaxDiff Scores, ACA OLS, or ACA/HB to a .CSV file, the resulting file would be incorrect if there were commas or quotes in the text being saved. This bug has been fixed.
  5. Sometimes the Alt-O, Alt-C, Alt-F4 and other shortcuts caused SSI Web to stop responding (or freeze up) at times on the CBC Settings, Prohibitions, and Global Format Settings dialogs. This bug has been fixed.
  6. When using the Export Open-Ends Only feature with "Internal Interview Number" selected as the Respondent Numbering, the values being exported for the internal interview number were not correct. This bug has been fixed.
  7. After running SSI Web for a while and doing lots of previews, SSI Web would sometimes begin to report run-time error messages and crash. This bug is described in greater detail here. This bug has been fixed.
  8. The numeric and open-end question input boxes did not align to center or right unless there was text entered into the 'Question' text field for the question. The bug has been fixed so that the input box now aligns correctly regardless of the existence of the question text.
  9. In Print Study "Text and Settings View" if the "Include HTML Tags" option was unchecked, and the study had foreign characters in it, then the resulting *.txt file would contain the '?' characters in place of the correct foreign characters. This has been fixed.
  10. When printing the study to a PDF, an "Unable to render HTML" error would sometimes occur with large files. This has been fixed.
  11. If the Progress Bar was placed in the Global Header and styles were applied, the Progress Bar would not be displayed correctly. This has been fixed.
The following changes have been made to SSI Web:
  1. The graphical next button used "<img " in v6.0.0. In v6.0.2 the Perl code converted this to "<input type="image" ". Now the GUI defaults to "<input type="image" ". When v6.0.0 and v6.0.2 studies are converted to v6.0.4, "<img " will be converted to "<input type="image" " automatically.
SSI Web 6.0.2 (2 Jan 2007)
The following feature has been added to CBC/Web:
  1. Show Levels of First Attribute no more than Once per Task. Sometimes with attributes like brand, the researcher wants each brand to appear exactly once per choice task. If you have 4 brands and are showing 4 concepts per task, this happens naturally with Complete Enumeration or Shortcut strategies--unless you have included prohibitions in your study. When prohibitions are in place, it is possible for a brand to be repeated within the same choice task. To avoid this possibility, you can check this box, and the designer will ensure that levels of the first attribute appear just once per task.
The following bug fixes have been made to SSI Web:

  1. When trying to append CBC paper and pencil data to existing data in a study the following error would occur:

    The study data file cannot be modified because it is read-only.

    Please change this file so that it can be modified and try accumulating again.

    even though the study's data file was not read-only. This bug has been fixed.

  2. SSI Web would crash when trying to enter CBC prohibitions with the CBC base system (CBC/Web 10) license only. This bug has been fixed.
  3. When using CBC Constant Sum where the respondent was not required to enter an answer into each concepts' input box, the respondent would not have been included in the .CHS file export if they did not answer the first concept of all of their tasks. This bug has been fixed.
  4. If a grid question is configured for the question direction to be "Rows", then clicking on the pencil button for any of the grid question's row list items (to edit the list item text in the SSI Web text editor) will cause SSI Web to crash. The same will occur when editing column list items when the question direction is configured as columns. This bug has been fixed.
SSI Web 6.0.0 (8 Dec 2006)
The following features have been added to SSI Web:
  1. Print Study. This feature allows you to print/save a copy of your questionnaire in two formats:
    1. Graphical View: a graphical PDF or HTML format that shows what the questionnaire looks like to the respondent as displayed by a web browser, with question name labels alongside each question for easy reference.
    2. Text and Settings View: a text-only format intended for internal review that includes many details about each question: question text, response options, answer settings (such as min, max, number of responses, randomization, etc.), skip logic, lists, constructed list logic, attribute and level lists, and conjoint settings.
  2. Quick-Print Functionality. In the previous version of SSI Web, there were many dialogs that contained information that we have wanted to be able to print or save to file for further review. These areas that now are quick-print enabled are: skip logic, lists, quota control, CBC conditional text and conditional pricing, prohibitions, conjoint attributes and levels, and the question list dialog.
  3. Enhanced SPSS Export. We now can export Variable Labels (question text) using text in your Header 1, Header 2, or Question text fields (we strip the HTML). You may choose whether to export multi-select questions as either checked/not checked fields or item numbers (previously, only checked/not checked was offered). With this new version, we also export variable names longer than 8 characters to SPSS, rather than truncating them.
  4. Improved Internationalization. In the previous versions of SSI Web, you needed to change your regional settings in Windows before working on a study that involved a different character set. This is no longer necessary, and the different character sets (such as double-byte characters to display Chinese) are displayed correctly in all dialogs and reports within SSI Web.
  5. Style Selector. A new Styles tab on the Global Settings dialog lets you select different Styles (implemented via CSS) to apply to your entire survey. This dramatically changes the appearance of your survey, creating some unique and professional displays. Select from the styles currently shipping with the software, or develop and import your own styles (by following our annotated CSS file format and editing it to your specifications). We have tested our style sheets across all supported SSI Web question types (including conjoint and MaxDiff).
  6. Graphical Next Button. Allows you to specify your own graphic (rather than just text) to use for the "Next" button.
  7. New Scriptable Settings Fields. In the previous version of SSI Web, you could provide dynamic fields (scriptable with SSI Script commands) instead of fixed values for settings such as the Min and Max permitted in a numeric question, or the total points to be allocated in a constant sum question. In v6, we have expanded the scriptable fields to include number of items to rank in a ranking question, and the min and max checks permitted in a checkbox question.
  8. New SSI Script Functions. QuestionName, DisplayTotals, SortbyLabel, PageNumber, TotalPages, NumChecked, TextExists
  9. Ability to Customize Look of Online Administrative Module. This is an advanced area, but if you follow our instructions for creating a .CSS file and uploading it to your graphics folder, you can put your own company's logo and title on the administrative module rather than Sawtooth Software's.
The following features have been added to CBC/Web:
  1. Dual-Response None Format. Some researchers are including the "none" alternative as a second-stage question in CBC studies. Respondents first choose among available alternatives (a standard CBC question, without the "none"), and then specify directly below whether they would in reality buy the product they just selected. The dual-response "none" increases the statistical efficiency of the study and leads to a stronger "none" parameter (which many researchers suggest is more realistic). CBC/Web v6 supports this questionnaire format. If using Sawtooth Software tools, estimation must be done with CBC/HB v4.
  2. Constant Sum Format. For some industries (such as pharma), researchers often employ constant-sum (allocation) questions in CBC. Respondents are asked to allocate some number of points (such as 100) across available alternatives, to reflect, for example, the probability of prescribing each medication to a specific population. CBC/Web v6 supports this questionnaire format. If using Sawtooth Software tools, estimation must be done with CBC/HB.
  3. Enhanced Prohibitions (between-concept, n-way prohibitions, null levels). The dialog has been improved to more closely resemble our SMRT software product (an older generation conjoint platform) for checking prohibitions. Additionally (for those licensed with the Advanced Design Module), we now support prohibitions for levels between concepts, rather than just levels within the same concept. This allows the researcher to specify (for example) that a specific brand-price combination cannot appear in competition with another brand-price combination. For Advanced Design Module users, up to n-way prohibitions (where n is the number of attributes in your study) can be specified, for both between- and within-concept prohibitions (previously, prohibitions between only two levels could be defined). Between-concept prohibitions are less detrimental to design efficiency than the traditional within-concept prohibitions. Also, if you are including null (often as "blank") levels within your attributes, you may now prohibit too many null levels from appearing within the same concept.
  4. Enhanced Test Design (logit report based on simulated dummy data, D-Efficiency). Previous versions of CBC/Web have used a test design algorithm based on OLS principles that does not consider that concepts are grouped in sets (wherein, for example, level overlap matters). While this tool has been quick and handy, it doesn't let you test advanced designs very competently (such as those with interaction effects or alternative-specific parameters), and it doesn't support the industry-accepted standard of simulated respondent data followed by computing relative D-efficiency. The new designer automatically simulates random respondent answers and produces a logit report (allowing you to study the pattern and magnitude of standard errors for the parameters) along with a relative D-efficiency statistic.
  5. Import/Export Designs. In the past, the only way (other than through a separate utility) to view your design prior to fielding was to import dummy respondent data via the paper-and-pencil module and then export the data as a .CHO file. Also, there wasn't a way (again, other than through a separate utility) for researchers who had developed a design elsewhere to import that design for use in CBC/Web. Both capabilities will be supported in v6, using an easy, rectangular Excel-compatible file format (.csv).
  6. Short Labels for Analysis (applies to attributes and levels). This allows you to assign short labels for use in subsequent part-worth estimation and market simulations (through SMRT).
The following features have been added to ACA/Web:
  1. Option to Drop Importance Questions. In two recent research studies, we found that dropping the importance questions resulted in better share predictions for holdout choice tasks using ACA/HB estimation. If sample size is relatively large and share prediction accuracy (rather than individual-level hit rate prediction) is the goal, then our research suggests that dropping the importance questions is the better way to go. If you drop the importance questions, prior importances (for purposes of designing the conjoint pairs) can be taken from previous respondents' data, or can be set to be equal.
  2. Ability to Customize Importance Questions. Of the sections in the ACA survey, the self-explicated importance questions are perhaps the weakest link. One of our clients had a need to collect self-explicated importance information through a constant-sum question (this client was surveying sophisticated financial analysts who were adept at allocation tasks) rather than using ACA's standard importance question format. In v6, we have made it possible for you to ask importance judgments using constant sum or any other question type that saves positive numeric values.
  3. Enhanced Randomization Options. Previously, you could not randomize the order of presentation of attributes (in the importance and ratings sections), and attribute levels within the level ratings section. That functionality is now available. Also, attribute positional order in the conjoint pairs section previously was always sorted by prior attribute importance (more important attributes appeared above less important attributes). You can now turn off that sorting if you prefer that attribute position follow natural order. (For example, if brand is the first attribute in your attribute list, it will always appear as the first attribute in a conjoint pair involving brand.)
  4. New Prohibitions Dialog. We have updated the prohibitions dialog to more resemble that of our older-generation SMRT conjoint platform (ACA for Windows). This dialog was generally preferred by users.
  5. ACA/HB Integration. If you own ACA/HB v3, its capabilities are now integrated within SSI Web's menus (or you can continue to use ACA/HB as a separate program).
  6. New SSI Script Functions. ACABestLevelLabel, ACAMostImpAttLabel, ACAStrictImportance

Version 5.4 History

SSI Web 5.4.10 (22 Mar 2007)
The following bug fixes have been made to SSI Web:
  1. The Grid Question Numeric Variable dialog box was not saving changes to the number of decimals. This only happened if the the checkbox indicating whether to allow decimals had not been clicked before pressing OK. Therefore, when you turn it on it would be saved, but re-entering the dialog and modifying the number of decimals and clicking OK would not have saved the new number of decimals. This bug has been fixed.
  2. After running SSI Web for a while and doing lots of previews, SSI Web would sometimes begin to report run-time error messages and crash. This bug is described in greater detail here. This bug has been fixed.
  3. If a CBC study has fixed choice tasks that have missing answers and are being imported using CBC paper-and-pencil, then a "type mismatch" error would happen. This bug has been fixed.
  4. Select, Grid, Constant Sum, and Ranking Question dialogs do not show the correct list randomization controls when the dialog first loads up with constructed lists. The predefined list controls were being shown. This bug has been fixed.
  5. The OK and Cancel buttons may disappear from the MaxDiff Scores Settings dialog and MaxDiff Cho Export Settings dialog if the Windows DPI setting is not the standard setting. This bug has been fixed.
SSI Web 5.4.8 (24 Apr 2006)
The following bug fixes have been made to SSI Web:

  1. If a respondent chose the "none" option for a fixed task in a CBC study then the following error would occur when exporting a CBC .CHO file:

    Unable to resolve answer for a CBC Fixed task.  Make sure that you have the correct design file, data file, and study.

    This bug has been fixed.

  2. Free Format Variable Checkbox type was enforcing the "Force respondent to check a certain number of boxes" (minimum and maximum) even though the option was not checked. This bug has been fixed.
  3. The Grid Question Numeric Variable dialog box was not saving a change to the number of decimals.  This only happened if the checkbox indicating whether to allow decimals had not been clicked before pressing OK.  Therefore, when you initially checked allow decimals it would be saved, but re-entering the dialog and modifying the number of decimals and clicking OK would not have saved the new number of decimals.  This bug has been fixed.
  4. In CAPI mode it was possible for existing individual data records to be overwritten by new data records. The likelihood of this happening would increase as the number of data records on a single CAPI interviewing computer would increase. (In CAPI mode Internal Respondent Numbers are randomly generated. If the random number conflicted with one already in use the existing data would be overwritten).
SSI Web 5.4.6 (5 Apr 2006)
The following bug fixes have been made to SSI Web:
  1. If fixed tasks were exported (using "File | Export All...") from a CBC study using random concept sorting, then the fixed task answers exported were not the correct answers when compared to the original fixed task design (in the SSI Web program).  The answer exported was the concept number that the respondent chose after the random concept sorting had been applied.  This bug did NOT affect the .cho export.  This bug has been fixed.
  2. SSI Web would overwrite other Sawtooth Software product user ids when imported through SSI Web.  No message boxes were shown to notify the user of the user id replacement or to ask if the user id should be replaced.  This has been fixed so that SSI Web will never overwrite non-SSI Web product user ids.
  3. Importing CBC paper-and-pencil data with respondent numbers greater than 1,679,615 would corrupt the respondent number.  Only the respondent number gets corrupted; all other data in the record are not affected.  The system will still not handle respondent numbers larger than 1,679,615 but now if the import encounters one it causes an error and the import is stopped.

  4. On some web servers the MaxDiff/Web design file header was not being read properly.  The result was that before the first MaxDiff set was shown the following error would be shown:

    Error:
    Exercise ID in MaxDiff design file (STUDYNAME_MXD1_1142613551.cgi) does not match exercise ID in the QST file.

    This problem has been resolved.

  5. If multi-line SSI Script (such as unverified perl) is contained in CBC conditional text, when the design is generated, the program will usually stop responding.  In some instances, it is possible that the design will generate correctly but incorrect or unexpected results may occur during respondent interviews.  This bug has been fixed.
  6. Change for MaxDiff score estimation: the way memory is managed during estimation has been updated. Large datasets (many parameters and/or many respondents) under some systems would run more slowly prior to this update.
SSI Web 5.4.4 (26 Jan 2006)
The following bug fixes have been made to SSI Web:

  1. When trying to accumulate CBC Paper-And-Pencil data an error message similar to the following was being shown (even though a valid CBC license was present):

    The number of current respondent data records (103) is greater than or equal to the number a demo study permits (5). No data records will be accumulated.

    This error has been fixed.

  2. Multiple operators in SSI Script may evaluate incorrectly. For example,

    (18 / 6 / 3) evaluated as (18 / (6 / 3)) instead of ((18 / 6) / 3)

    (18 / 6 * 3) evaluated as (18 / (6 * 3)) instead of ((18 / 6) * 3)

    This behavior was experienced with the division, subtraction and mod operators. This has been fixed.

SSI Web 5.4.2 (28 Dec 2005)

MaxDiff/Web Demo is now available in the SSI Web platform. Be sure to read the release notes for SSI Web 5.4.0 below.

The following bug fixes have been made to SSI Web:
  1. SSI Web 5.4.0 did not allow creating CBC Paper & Pencil files. This has been fixed.
SSI Web 5.4.0 (14 Dec 2005)

MaxDiff/Web is now available in the SSI Web platform. For information on MaxDiff/Web, including purchase information, please visit the MaxDiff/Web product page on our website.

This version uses new User Ids for all product components (CiW, ACA, and CBC). Before you install this version, contact Sawtooth Software to receive new compatible User Ids.

Authoring surveys using Windows 98 and Windows NT are no longer supported. SSI Web 5.4.0 will not install on a Windows 98 or a Windows NT machine.

The following enhancements have been made to SSI Web:
  1. The maximum number of concepts per task in a CBC ADM study has been changed from 101 to 251 (250 concepts if the none option is included, 251 concepts without the none option).
  2. The maximum number of levels in a CBC ADM study has been changed from 254 to 250.
The following bug fixes have been made to SSI Web:

  1. Exporting either the "Start Date/Time" or the "End Date/Time" variable to the Excel (.xls) file format on a computer with the operating system's regional settings configured to use a comma as the decimal character would create a file that could not be opened by Microsoft Excel. When attempting to open the file in Excel, an error would display the following message:

    Problems came up in the following areas during load:

    Table

    This file cannot be opened because of errors.

    This bug has been fixed.

  2. Uploading CBC design files in ASCII text mode to a UNIX server would corrupt the design files. A check has been added to make sure that the design files have not become corrupt by uploading in ASCII mode. SSI continues to recommend that all files be uploaded to the server in binary mode.
  3. If the Quota Cell Qualification check point was moved (after data collection has begun) to a point further along in the questionnaire list, there was the possibility that some respondents had data erroneously removed and stored in the Limbo data folder. This has been fixed.
  4. In the Online Administrative Module, under View Data, a data record would have JavaScript = Yes even if they did not have JavaScript enabled. The raw data file correctly stored "sys_JavaScript, 0" but the Online Administrative Module would incorrectly interpret that and display JavaScript = Yes. This has been fixed. This bug was introduced in version 5.0.0 of the software.
  5. In Constant Sum and Grid Constant Sum questions, if the constant sum "min" (under the advanced tab) equals the constant sum "total" (on the main dialog), e.g. both are 100, the verification would not take place to see if it adds up to the proper range. This has been fixed. This was introduced in version 3.0.

Version 5.2 History

SSI Web 5.2.2 (28 Jul 2005)

Due to our ongoing development to better support internationalization, this version may not install correctly on Windows 98. If you use Windows 98, please contact Sawtooth Software and we will guide you through the installation process.

The following enhancements have been made to SSI Web:
  1. The software capacity has been increased for Academic Licenses. This includes the number of attributes in CBC and ACA (now 10), the number of CiW questions (now 500), and the number of respondents (now 250).
  2. Saving to a network drive should perform faster.
  3. Exporting should perform faster.
  4. Study Check, Prepare for Web and Preview should perform faster.
The following SSI Web bug fixes have been made:
  1. If a respondent tried to log into a survey after they had already completed it, and the data record had been accumulated, the respondent previously would see "Sawtooth Software Error #9". This has been corrected, and the respondent now sees "No additional interviewing permitted using this username-password combination." (This bug was introduced in SSI Web v5.0.)
  2. If an attribute level in ACA came from a constructed list, then it would be possible that the limbo data cleaner would clean data that it was not supposed to. This has been fixed.
  3. When naming or renaming a question name, list name, or quota cell name, invalid characters were allowed if the characters were pasted using a keyboard short cut (Ctrl + V) or using the mouse right click menu. If you try to open a study containing such a name, the study will not open. A message is shown that a name was encountered with invalid characters. Please contact Sawtooth Software for help opening the study.
  4. Previously, the list of export symbols saved in the .ssi file would double each time the write questionnaire dialog was closed without saving changes. This caused the .ssi file to potentially become very large and take a long time to load and save. This has been corrected.

  5. A compile error similar to the following:

    Error Question 'Grid1' Grid Rows - Row 9 Settings - Combo Box Response Options - The list 'Grid1' ComboList8 does not exist.

    would occur if a grid question with combo box type ranking variables had been copied from one study to another study due to the list associated with the combo box type ranking variable not being copied along with the question. This has been fixed.

  6. We've fixed the ROUND() function in SSI Script so that trailing zeros are not improperly truncated. For example ROUND(5.1, 2) now correctly returns 5.10 rather than 5.1.
SSI Web 5.2.0 (19 Apr 2005)
The following features have been added to SSI Web:
  1. Quota Control. Quota Control can close the survey to new respondents after a certain number of completes. Quota Control may also be used to achieve a sample reflecting known characteristics of a population: representative proportions of male, female, low income, high income, etc. As an example, once enough "male" respondents have completed the survey, new males will not be permitted to fill out the survey (once gender is determined).
The following features have been added to CBC/Web:
  1. For the Advanced Design Module, we have increased level capacity per attribute from 100 to 254. Though we think it is a rare event that would call for so many levels of an attribute, and we are cautious about the analysis implications, some clients have asked for this capacity.
The following SSI Web bug fixes have been made:
  1. Start Date / Time and End Date / Time values did not export to the .CSV or the .TAB file formats correctly. They exported just a single digit "2" or "4".
  2. When a numeric-type answer was not answered by the respondent (either because the question was skipped by the respondent, or because the question was not required), the answer was exported as a zero (0) instead of being an empty cell when exported to the "Microsoft Excel 2002 or Later" file format.
  3. When converting studies to version 5 from prior versions, if there was a numeric-type question with decimals allowed, and the min or max had a decimal in it, the HTML created for that question would have an incorrect text box length. For example, if the Min was 0 and the Max was 10.5 then the input box created in the HTML would only allow two numbers to be typed in. 10 or .5 could be entered but not 10.5.
  4. When Exporting to the "Microsoft Excel 2002 or Later" file format while Microsoft Excel had the file opened (or any other program), SSI Web reported that respondents were successfully added to the file. After that, run-time error "-2147024864 (80070020)" would be displayed with the message "The process cannot access the file because it is being used by another process." SSI Web would then crash. No respondents would have been exported.
  5. When using some of the questions that are based on a predefined list (grid, constant sum, or ranking), if the option to randomize the order in which the list items are used in the question was chosen and then the list was then changed to a constructed list, the items were shown in the question in a randomized order when they should not have been.
  6. Using the "Randomize Response Options" checkbox on a question would give the same randomization sequence to all questions appearing at the same page position. For instance, suppose select question Q1 has response options 1,2,3,4. Also suppose that the response options had been randomized by checking "Randomize Response Options." If Q1 was the first question on a page the randomization might be 2,1,4,3. If another question, Q2, was the first question on a different page with randomized response options 1,2,3,4, the randomized order would also be 2,1,4,3. If a third question, Q3, was on a different page with randomized response options A,B,C,D, the randomized order would be B,A,D,C. This behavior with randomization could be found in Selects, Grids, Constant Sum, and Ranking.
    NOTE: This bug was NOT in the randomization of constructed lists with the RANDOMIZE() function. It was caused by using the "Randomize Response Options" checkbox on the question level, which is only available when using predefined lists.
  7. When using SSI Script, a script-ending marker ( %] ) without a matching beginning marker ( [% ) caused subsequent SSI Script to not be verified or translated for use on the server. For example, the following in the body of a Text question would not work: "%] Hello [%UserName( )%]".
  8. After changing the color of Error Message text to "Dk. Blue" in the global settings dialog, SSI Web would report the following error: "Custom Color must be a 6-digit Hexadecimal number such as "C7F2B4"". This has been fixed and new colors were added.

Version 5.0 History

SSI Web 5.0.4 (11 Mar 2005)
The following enhancements have been made:
  1. In order to better handle double-byte character sets and to enable multilingual studies the following study files now use Unicode (UTF-8) encoding:
    • STUDYNAMEqst.cgi (server study file)
    • STUDYNAMEdat.dat (study's data file)
    • STUDYNAMEctxt.cgi (CBC conditional text file)
    • STUDYNAME.txt (Open-end export)
    • STUDYNAME.csv (Export All file type)
    • STUDYNAME.tab (Export All file type)
    • STUDYNAME.lay (Export All file type)
    • STUDYNAME.att (CBC attribute information file)
    • STUDYNAME.aca (ACA attribute information file)
  2. Microsoft® Excel® file format (for Excel XP® (version 2002) and later versions) was added to the list of available export types.
The following bug fixes have been made:
  1. With some non-Western language surveys (in particular Asian languages) if a certain character was entered in the survey text error messages it could cause JavaScript verification to break. Also if this character was entered into ACA or CBC headers or footers the resulting text would not look correct.
  2. Only the first instance of the following ACA keywords:
    • [%ACAATTRIBUTE()%]
    • [%ACABEST()%]
    • [%ACAWORST()%]
    were replaced with the appropriate text from the attribute/level text per header. All instances are now replaced.
  3. Ranking questions counted against the CiW license size always using the size of the list (or parent list) used in the question, even if only a sub-set of those options were required of the respondent to rank. Now, as many questions count agains the license as are ranked.
  4. If a study created with SSI Web versions earlier than version 5.0.0 had never used an Export All operation, then when the Export All option was chosen in the converted study the Export All dialog would not work correctly. Now in this case the .CSV file format will be chosen by default.

  5. When using Japanese Attributes or Levels sometimes the Perl Scripts would report the following error when the survey is run (either in local web or on a web server):

    Error: Problem reading QST section:

    Bad name after _ow' at (eval 15) line 1, line 14.

  6. If the entire question name was selected when editing it on the "New Question" dialog or on the "Rename Question" dialog then the backspace key would not work for deleting the question name.
  7. Pre-skips to another question on the same page would go to that question and not show any other question before it on the same page. So if Q1, Q2, and Q3 were all on the same page and if Q2 had a pre-skip to Q3 then Q1 would not be shown.
  8. When an attribute was deleted in CBC when a CBC partial profile design had been specified (a feature of the Advanced Design Module), multiple errors could happen, perhaps in combination:
    1. If randomizing a subset of attributes, the attributes being randomized could be changed erroneously without a warning
    2. The design could change from partial profile to traditional without a warning
    3. The design could change from full profile to traditional when it should not have changed
    4. The design could not change from full profile to traditional when it should have changed
  9. The data accumulation process that is invoked by the "Get Data" option within the Online Administrative Module has been improved. Previously there was a possibility that if a server error occured during the accumulation process that the data being accumulated could be lost. The data accumulation process has now been improved to minimize any possibility of data loss in the event of a server error.
SSI Web 5.0.2 (13 Dec 2004)
The following bug fixes have been made:
  1. The following bug only affects SSI Web when running on a double-byte version of Microsoft Windows® (such as Japanese or Simplified Chinese). SSI Web reports "WCK Error#15Nov2004" when the "Generate / Test Design" button is clicked and the study that is currently opened is in a location with double-byte characters in one of the folder names.
  2. The following bug only affects SSI Web when running on a double-byte version of Microsoft Windows (such as Japanese or Simplified Chinese). SSI Web reports "Problem reading QST section" when you try to preview a study or run it in local web or on a web server and the study contains double-byte characters.
  3. The Hex Color codes (such as FF3012) cannot be copied or pasted.
  4. The following bug only affects SSI Web when running on some double-byte versions of Microsoft Windows (such as Simplified Chinese). (This bug does not affect SSI Web when running on Japanese versions of Microsoft Windows.) SSI Web reports "The offsets in the STUDYNAMEqst.cgi file are incorrect. ..." when you try to preview a study or run it in local web or on a web server. This error will occur whether you have double-byte characters in your study or not.
  5. Version 1.5.5 studies with numeric questions would not convert to version 5.0.
SSI Web 5.0.1 (15 Nov 2004)
The following bug fixes have been made:
  1. Respondents were not able to restart their surveys if their User Name or Password was typed in upper-case (surveys actually restart, but at the beginning of the survey). This only occured on Unix based web servers.
  2. Deleting individual data records in the On-line Data Management Module under View Data would not (if the User Name or Password was entered in upper-case) allow respondents to restart. This only occurs on Unix based web servers.
  3. Password reports could be incorrect if the User Name or Password was entered in upper-case.
  4. If the survey error messages were customized, and hard returns were entered into the error messages, then JavaScript error verification would break. This would enable respondents to submit a page without that page being verified for respondent errors.
  5. JavaScript verification for "Other Specify" breaks on older browsers (I.E. 5.0, and some Mac browsers). This would enable respondents to submit a page without that page being verified for respondent errors.
  6. There were a few potential problems with running Mod_Perl in version 5.0.0. There was a potential issue with the CBC design file path, and another potential problem with the Online Administrative Module. If you are running SSI Web 5.0.0 under Mod_Perl you need to update to 5.0.1. Call Sawtooth Software with any additional questions.
  7. The Online Administrative Module was not compatible with older versions of Perl (v. 5.004). The effect was that the Online Administrative Module would not work at all. A server error would display to the screen.
  8. SSI Web reported an error when trying to create a new study, open an existing study, or trying to "save as" the current study using a network location that starts with \\.
SSI Web 5.0.0 (19 Oct 2004)
The following features have been added:
  1. Constructed Lists. One of the most important developments in v5 is the ability to create customized lists of response options for respondents, based on answers to previous questions, or other list-building logic or randomization functions. As one example, you might first ask respondents to indicate which of many brands they consider, then ask follow-up questions regarding each respondent's considered brands. (If you are a previous Ci3 user, it may interest you to know that CiW can now do all of the List Building examples in the Ci3 manual, adapted for the Web interviewing environment.)
  2. Predefined lists. With v5, all response options you specify for Select-type, Ranking, Constant Sum, and grid questions become lists that may be re-used in other questions (by selecting them from a drop-down list), or can be used to build customized (constructed) lists.
  3. More powerful Skip Patterns. In v5, skip instructions are user-specified (using typed syntax), and therefore more flexible than before. Previously nine and/or conditions were available per skip instruction, but now there is no limit to the conditional complexity. Skips are now question-based rather than page-based, so one indicates questions to jump from and to rather than pages (this will solve the headaches with previous versions involving checking whether skip patterns have been broken due to page inserts or deletes). In addition to the typical skip that is executed after a question is answered, "pre-skips" are now also offered. Pre-skips conditionally skip a question (prior to displaying it) if a certain condition is true. Pre-skips are very useful, and can be used to conditionally show the questions on a page that apply for a respondent.
  4. Paste lists of response options from Microsoft Word or Excel. Many users already have their questionnaires prepared in Microsoft Word. In v5, you can paste an array of response options from Word or Excel directly into a question or pre-defined list in one step. This offers an enormous time savings, as previously each response option had to be copied into the list of response options one list member at a time. For ACA/Web and CBC/Web users, you can also paste lists of attributes and levels from Word as well.
  5. "Other Specify" responses. Previous versions of SSI Web did not formally support an "other specify" response option in Select-type questions. In v5, you indicate which option(s) on the list are "other specify" responses, and SSI Web automatically adds a text entry field next to the option. You can ask SSI Web to verify that if the "other specify" option is checked, the respondent must provide text. Also, SSI Web automatically verifies that if open-end text is provided, the "other specify" option has been checked.
  6. Exclusive ("None of the Above") response options. Previous versions of SSI Web did not formally support "none of the above" (exclusive) response options. Users had to write skip logic (or JavaScripting) to verify that respondents did not check a "none of the above" option together with any other options in the list. You can now easily indicate which option(s) are exclusive, and SSI Web automatically verifies that respondents do not check multiple boxes including the exclusive option(s).
  7. New interface. We've redesigned SSI Web to consolidate the main Write Questionnaire area (the separate Layout dialog is gone). We've worked to shave extra "clicks" from standard tasks, so you can work even faster.
  8. Partial ranking in Ranking questions. Previously, respondents were required to rank all response options in a ranking-type question. Now, you can specify how many options are to be ranked. This is useful if you want to ask respondents to rank their top three brands, etc.
  9. Ability to Randomize Pages. In addition to being able to randomize questions on a page, v5 can now also randomize consecutive pages.
  10. SSI Scripting. A variety of mathematical and string operation functions are available within "SSI Scripting." SSI Scripting offers programming instructions that can be executed most anywhere within the software. You can create new variables as hidden variables and modify them using mathematical functions with SSI Scripting.
  11. Cleaning of "limbo" data. When respondents back up in a questionnaire and take a different path forward (due to skip patterns), v5 now deletes the data that are no longer valid ("limbo" data). For example, consider a questionnaire in which a respondent branches one way or another depending on company size. Consider a respondent that answers a few questions in the "large company" branch, and then backs up and changes the company size answer to "small company," then completes the questionnaire down the "small company" branch. SSI Web removes any answers in the "large company" branch of questions, recognizing that those data are no longer valid.
  12. New Terminating/Link question type. This new question type makes it easier to link multiple surveys together, as it leverages the standard Next buttons in the survey and re-directs respondents to a user-specified path, rather than relying on customized hyperlinks (such as a "Next" button graphic you have captured).
  13. Ability to customize the look of SSI Web surveys using CSS hooks and Style Sheet templates. Cascading Style Sheets let you modify the appearance of surveys beyond the look provided by standard font and color selections. With v5, we have provided "key word" hooks into nearly all aspects of SSI Web questionnaires (headers, footers, question text, table parameters, etc.).
  14. Ability to repeat the "column labels" in long grid-based questions. For example, after every 10th row in a ratings table, you may wish to repeat the scale header text used in the columns. That way, if respondents need to scroll down a large table, you can periodically repeat the column labels so that they do not have to scroll to the top of the table to review them.
  15. Improved method of launching Simple Browser. Simple browser provides a method for removing the browser's standard buttons. However, many respondent's browsers have interpreted the Simple Browser window as a pop-up to be blocked. We now get around pop-up blocker software by having Simple Browser create its new child window based upon the click of a button on an introductory page rather than spawning an unsolicited pop-up like in previous versions.
  16. Faster performance on server with Mod_Perl. SSI Web v5 is compatible with Mod_Perl. If you have Mod_Perl installed on your server, your surveys will experience a significant performance improvement, allowing more respondents to take surveys at the same time.
  17. Easier preparation of files for server deployment. With v5, the software automatically prepares the folder and sub-folders required for web installation for you (rather than you bringing the files together manually from multiple places). SSI Web creates a "Web Upload" folder within your study folder that contains all files needed for web interviewing. In most cases, this means you can simply drag-and-drop the contents of the "Web Upload" folder onto your server.
  18. Totals row/column available within grids using numeric questions. This is a non-editable field that automatically sums up the values that a respondent enters across a row or a column in a grid. Previously, totals rows/columns were only available within constant sum questions.
  19. Improvements to the Online Administrative Module. These include:
    • New "Crowd Control" feature (ability to close the survey after a certain number of completed records).
    • New Test Survey Mode (including Administrative Module tools for managing test data).
    • Response option labels are now provided for select-type questions in marginals.
    • Ability to view/delete specific records.
    • Ability to download and analyze incomplete data without removing it from the server.
    • Condensed study summary table that is easier to read and understand.
    • More direct method for accumulating/downloading data.
The following bug fixes have been made to ACA/Web:
  1. Modified the way levels are selected to increase the randomness of the combinations of levels selected within attributes. Previously if you had attributes with a large number of levels (more than 5), you could notice patterns in the levels selected across pairs for that attribute. This did not affect the estimation of the part worths. For an individual, the design was not as efficient as we intended.

Version 3.5 History

SSI Web 3.5.4 (13 Jan 2005)
The following bug fixes have been made:
  1. The "Specify Prohibited Pairs" dialog box may not show the correct attribute and/or level text for the prohibitions specified in the study if the attribute and/or level text contains tab characters or if it is multiple lines.

  2. SMRT may report the following error when trying to import a STUDYNAME.cho and STUDYNAME.att file exported from an SSI Web study that has level text that is more than 256 characters long and is more than just one line (these conditions will not always cause this error):

    "Error: The file 'STUDYNAME.att' contains information in the '/@ section' that is inconsistent with the 'level information section' at the beginning of the file."

  3. If passwords were entered in upper case by the respondent then that password would not appear in the password reports in the admin module.
  4. When ACA utilities are calculated from SSI Web where any of the attribute text has more than one line then the resulting .aca file will be corrupted and will not import into SMRT and will give an error message when you try. Now multi-line attribute text is collapsed into one line when it is exported to the .aca file.

  5. SMRT reports the following error when trying to import a STUDYNAME.cho and STUDYNAME.att file exported from an SSI Web study that has attribute text that is more than just one line:

    "Error: The file 'STUDYNAME.att' contains information in the '/@ section' that is inconsistent with the 'level information section' at the beginning of the file."

SSI Web 3.5.2 (23 Feb 2004)
The following bug fixes have been made:
  1. Bug fixed in CBC Conditional Relationships. Studies with a large amount of Conditional Relationship text would cause the *.cho file to be created incorrectly.
SSI Web 3.5.1 (20 Jan 2004)
The following enhancements have been made:
  1. New ACA and CBC Tutorials.
  2. Password reports in the Online Administrative Module are now more flexible.
The following bug fixes have been made:
  1. The Online Administrative Module now accumulates all data and does not use the STUDYNAMEqst.cgi file to filter out responses. Previously if questions were removed from the STUDYNAMEqst.cgi and then the data was accumulated there was a possibility that data would be lost.
SSI Web 3.5.0 (11 Nov 2003)
The following features have been added to SSI Web:
  1. We have added new capabilities for CAPI data collection. CAPI data collection lets you easily set up Web studies to run on stand-alone PCs or laptops for data collection (that are not connected to the web). We hope this new functionality makes SSI Web even more useful than before, allowing users to use the software in more traditional interviewing environments.
The following features have been added to CBC/Web:
  1. For the Advanced Design Module, we have increased level capacity per attribute from 15 to 100, and have increased the number of concepts that can be displayed per task from 16 to 100. These changes are particularly useful for packaged goods and beverage research, where it is common to have dozens of brands or SKUs.
  2. Conditional Pricing and Conditional Display capabilities. Users can now specify conditional pricing tables which enable them to create customized price ranges for certain brands (for example), or combinations of attributes (such as brand/package size combinations). Prices can be made to vary (using conditional "look up" tables) on the level combinations of up to three other attributes. Conditional Display lets users display a graphic (or other HTML element) in place of (or in addition to) an attribute's regular level text. Conditional display can vary these conditional elements based on the level combinations of up to four other attributes.
  3. Ability to suppress concept randomization. Some researchers have wanted their CBC tasks to always show a particular brand in a certain concept position on the screen. The default behavior in CBC is to randomize the position of levels on the screen. We've added the capability to suppress that randomization and show the concepts in a specific order (the natural order) for a user-specified attribute, such as brand. Thus, brand 1 will always display in the first concept position, brand 2 in the second position, etc. Another new feature randomizes the concept position once for each respondent (for a user-specified attribute), but holds that random order constant across all tasks for that respondent. This helps control order bias across respondents without making respondents re-orient themselves to the new positions of, say, brands on the screen within their respective surveys.
  4. Shelf-facing display presentation. We've added a new capability to the Advanced Design Module for showing realistic shelf-facing displays, like a shopper might see in a grocery store.
  5. Paper-and-Pencil Data Collection. Users can now use CBC/Web software for implementing paper-and-pencil CBC studies. The menu items are nearly identical as for CBC for Windows (SMRT). Also, we've changed the naming convention from "beginning questionnaire version" to "design seed" (though the functionality is the same). In CBC for Windows (SMRT) the beginning questionnaire version really was a design seed, and we've clarified that terminology both in SSI Web v3.5/v5.0 and in the newest version of SMRT to reflect that. Now, questionnaire versions always start with #1, but the designs can vary depending on the design seed.

Version 3.0 - 3.2 History

SSI Web 3.2.6 (13 Jan 2005)
The following bug fixes have been made:

  1. SMRT reports the following error when trying to import a STUDYNAME.cho and STUDYNAME.att file exported from an SSI Web study that has attribute text that is more than just one line:

    "Error: The file 'STUDYNAME.att' contains information in the '/@ section' that is inconsistent with the 'level information section' at the beginning of the file."

  2. SMRT may report the following error when trying to import a STUDYNAME.cho and STUDYNAME.att file exported from an SSI Web study that has level text that is more than 256 characters long and is more than just one line (these conditions will not always cause this error):

    "Error: The file 'STUDYNAME.att' contains information in the '/@ section' that is inconsistent with the 'level information section' at the beginning of the file."

  3. When ACA utilities are calculated from SSI Web where any of the attribute text has more than one line then the resulting .aca file will be corrupted and will not import into SMRT and will give an error message when you try. Now multi-line attribute text is collapsed into one line when it is exported to the .aca file.
  4. If passwords were entered in upper case by the respondent then that password would not appear in the password reports in the admin module.
  5. The "Specify Prohibited Pairs" dialog box may not show the correct attribute and/or level text for the prohibitions specified in the study if the attribute and/or level text contains tab characters or if it is multiple lines.
SSI Web 3.2.4 (19 Jan 2004)
The following enhancements have been made:
  1. New ACA and CBC Tutorials.
  2. Password reports in the Online Administrative Module are now more flexible.
The following bug fixes have been made:
  1. The Online Administrative Module now accumulates all data and does not use the STUDYNAMEqst.cgi file to filter out responses. Previously if questions were removed from the STUDYNAMEqst.cgi and then the data was accumulated there was a possibility that data would be lost.
SSI Web 3.2.3 (11 Nov 2003)
The following bug fixes have been made:
  1. ACA Web updating bug (too much weight placed on priors)
  2. Errors in %%ANLN% display variables
SSI Web 3.0.1 (26 Aug 2002)
The following enhancements have been made:
