How should I setup my choice experiment data to avoid this error during -cmset-?
"at least one choice set has more than one instance of the same alternative"
Specifically, should be the "opt out" option be entered? I believe it is the source of this error as it is present in all the choice sets (see column EQPTALT).
Here is a sample data from one respondent
