I need to test the IIA assumption with a multinomial logit
model. I have used the mlogtest,all command, but get the following error
message:
Data has been altered since mlogit was estimated.
I suspect it is since I had to use the ice command to impute
missing data and the actual estimation command is micombine mlogit........
Can anyone advise me on the best way to test the IIA
assumption in this case?
Thanks in advance,
Julie
