I did two experiments and found different results! I wonder why the results of the two experiemnts are different?
- Experiement #1: I sorted first the data by "caseID", where CaseID is the unique ID of the respondents. Then, using caseID as subject, I successfully run the syntax and saved the utilities. I think it is called individual conjoint analysis. Subsequently, using such utilities data , I computed the utilities for the gender, marital status, and religion groups.
- Experiment#2: I sorted the data by gender and run the syntax using gender as subject. I did the same for the other grouping variables.
Thanks.
