How can I get the Utilities for a part of data?

Ich have made a CBC Questionnaire on the SSI web and got 250 Participants. Now, I want to divide 250 Participants into 3 groups and run the Utilities för each group. the Utilities from such 3 groups will be later compared.

When you go to calculate the utilities, you can click "Settings..." and select the relevant filter in the Respondent Filter section.

If you are referring to HB estimation, don't forget the notion of using covariates in HB and estimating the model together.  Then, post hoc filter the results to separately look at the three groups.  This is often considered a stronger approach statistically than dividing into 3 groups and running HB separately on the groups.
