Dear Wasin,

In order to perform a CBC with a group variable, you need to add first a column in your CBC design containing the group category for each individual. Then, select this variable in the Group Variable field of the CBC dialog box. Note that you can use one group variable at a time. and that only qualitative variables are accepted.
Let us know should you have any further questions.
Regards,

Dear Tabea,

In order to perform a CBC with a segmentation (group) variable, you need to add first a column in your CBC design containing the group category for each individual. Then, select this variable in the Group Variable field of the CBC dialog box. Note that you can use one group variable at a time. and that only qualitative variables are accepted.

I will also send you a demo file by email.

Hi!
I understood the structure of the data that contains the group variable.
However, if you assign 5 cases to group (eg male, female) variables in demoBC_en.xls,
it seems that the aggregated utilities have an error.
