Dear All,
I need to run a mixed logit model in Stata that include also a no-buy option. I have 3 factors with two levels (-1 and 1) plusprice (3 levels). In each choice set I have 3 alternatives which are 2 product combinations + no-buy option.
I have experience with mixed logit model without no-buy option (ie. 3 alternatives which are 3 products) so forced choice using a model like this:
mixlogit choice, rand(fact1 fact2 fact3 price) group(setid) id(id) nrep(100).
So, now my question is if I have the no-buy option, how the model will change?
Also how to code it the .dta file? I guess that I need to have an extra column called "no-buy option", so where to put -1 or 0 and 1?
Thanks a lot for the help,
Daniele
