st: Hausman test for Independence from irrelevant alternatives

[hsk22@cam.ac.uk]

Dear STATA users,

I would like to ask a question. I want to run a conditional logit and I 
have 3 alternatives such as C:keeping current policy (baseline group), 
A:protection policy (1), B:protection policy (2).

I run conditional logit model by using clogit command and got the results. 
I would like to test IIA violation when I drop one of alternatives (A or B) 
by using Hausman test. How can I set up STATA command. According to help 
menu, there is some example of mlogit not clogit. I will be appreciated for 
any comment on this. Thanks in advance.
