Hi all, i am using xmelogit to estimate the model where some IV are categorical. when i am trying to use IV which are categorical predictors with more then 2 levels (i.e. not just 0/1 - those are added without problems) e.g. i.status , where status values are A to F (encoded as numbers) i receive a following message: "numerical derivatives are approximate flat or discontinuous region encountered" what does it mean? i dont use those variables correctly? thank you * * 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/
