Additional variables that were not collected may be merged to the data using the Add Merged Variable button. When this is clicked, a dialog appears asking for the variable name and data type. The variable name must be a valid Lighthouse Studio name. Regarding data types:
Usually discrete integers starting with 1, such as 1=male, 2=female, 3=refused. Usually used for a nominal scale, where the researcher specifies labels for each category. The size of the numbers typically has little or no meaning for the analysis. During analysis, may be used for filters/segments/covariates.
Numeric values associated with quantities such as income, age, etc. where the size of the numbers has meaning. Can contain decimal places of precision. During analysis, may be used for filters/segments/covariates and weighting.
The data may contain letters, numbers, and special characters (such as !, $, ^, etc.). During analysis, may be used for filters/segments, but may not be used for weighting.
