following up on I discussion I recently read about ACBC design efficiency, I´d be grateful for your opinion on the efficiency of the following design.
In my ACBC (8 attributes, 4 prohibitions) I conducted the design test with the following results:
- Out of 300 robotic tests, only 1 respondent had a minium of 1 view/level. Thus, the design in general is efficient but partially sparse.
(Is that a sound conclusion?)
- The highest standard error for a level is 0.037 (average of 0.025) and thus below 0.05
- The average D-Efficiency is ~0.979
In this regard, I have a couple of questions.
*What is the maximum possible value for the D-Efficiency?
*In general these results indicate a valid and rather efficient design, right?
*After the real fielding, do you recommend to analyze these indicators again and where do I find the standard error and d-efficiency for the real data?
Thank you very much in advance for your support.
