I can't replicate the problem. Do you have the latest version of the

your version of Stata is up to date. mlogtest itself was last
updated in December:Hi Statalisters:
I ran a multinomial logistic regression with a 3-category dependent
variable (the IVs include one continuous variable and 8 dummies), and
wanted to test the IIA assumption. The problem is that -mlogtest- will
not perform the Hausman test. I used the -mlogtest- command after
running -mlogit-, in different versions: I tried -mlogtest, iia-,
-mlogtest, hausman-, and -mlogtest, smhsiao-. Stata will do the
Small-Hsiao test, but it won't run the -mlogtest, iia- and -mlogtest,
hausman- because of "invalid syntax". I Googled generally and
searched the Statalist archives, but have not come across anything
directly relevant. Am I missing something? What might be causing this?

If everything is up to date, perhaps you could try to see if you can
come up with a replicable example using a publicly available data
set, e.g. auto. You may need to contact Scott Long if you think
you've discovered a bug in his program.
Also, these commands work for me, so see if they work for you:
