Farmers were asked to choose 2 of the 6 options, and then to choose the specific option 1/2/3/4 from among the options, which was equivalent to two responses per farmer.
I use the code “mixlogit choose input_goal tax_sup guide_sup segment_sup regulation_sup sale_goal ,group(group) id(ID) rand(age edu exp risk scale breedingtype tech_way clean_way harmless_way) .But it showed “At least one group has more than one chosen alternative”.
I have studied Mr Yoo's responses to the relevant questions, but I still don't know what the problem is. I’ve submitted the dta. file in the attachment. I would appreciate if you could teach me how to solve it .
