Hi Wilner. Thank you very much for the response. I am actually running a latent class model and so the logit is indeed the correct distributional assumption to assume in this case. There are two further queries I have based on your question. My variables (miles5, miles8, asc etc.) are all effects coded variables. miles5, for example, is only one of the 4 levels of the distance attribute and so I have the variables coded as follows: miles5 miles8 miles12 miles5 1 0 0 miles8 0 1 0 miles12 0 0 1 miles18 -1 -1 -1 The asc variable is simply coded as 1 for the status quo and zero otherwise. And price is the only continuous variable in the model. Besides this, I have interactions between the different effects coded variables. Do I enter the average based on the effects codes in the mymean() vector? Or is there a different approach to take? Also, given I currently only have the varcov matrix and the coefficient estimates vector in stata - would it be enough to "trick" -wtpcikr- by trying to run a logit model which results in an error? If not, I guess I'll just have to append the current dataset with a few data entries that would allow for running a logit. Thanks a ton for the help. Kind regards Sanja * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
