Dear Statalist,After running the multinomial logistic regression model, I would like to test the independence of irrelevant alternatives assumption (IIA). However, I heard that the Stata command "mlogtest, iia" no longer works with factor variables. So, what Stata command should I use to test the IIA assumption?Thanks, Patricia
-mlogtest- is a command written by Long and Freese that is part of their -spost9- package. I imagine the easiest thing would be to just not use factor variables; compute any dummies yourself if necessary.
