Hello,
I am doing a mixlogit regression for a DCE.
This is the command that I am using- mixlogit choice smartfeature, id(id) rand(highenergyefficency mediumenergyefficiency lowenergyefficiency) group( iid)
I collected this data regarding the preferences of consumers. When I try to run this without medium e.e, the p-value comes out to be very high but the regression does run. whereas, In all other cases, the regression does not run and shows the following message- "Some variables are collinear - check your model specification".
I will really appreciate all the help that I can get.
Thank you.
