Dear all,
I would like to ask a question. I want to run a multinomial logit and I
have 6 alternatives:
1. not working and not using child care (baseline group)
2. not working and using child care
3. working part time and not using child care
4. working part time and using child care
5. working full time and not using child care
6. working full time and using child care
When I try to test the hypothesis of Independence of irrelelevant
alternatives, by typing mtestlog,hausman,
I get the following error message:
*** Hausman tests of IIA assumption
Ho: Odds(Outcome-J vs Outcome-K) are independent of other alternatives.
no coefficients in common; specify -equations(matchlist)-
for the problem of different equation names.
r(498);
Why is that?
Many thanks in advance for your help
Best
Marilena
