R help - Feb 2015 - Hausman test for Conditional Logit

Dear all,

I am running a conditional logit model on migration choices using the 
"mclogit" package, and I would like to test the independence of 
irrelevant alternatives (IIA), as it is a restrictive assumption of 
those models. The mclogit package does not offer the Hausman test, which 
seems to be the most widespread. The package "mlogit" does, but it 
doesn't deal with conditional logit models. Does anybody know of a 
package, or has a code to do this?

Thanks in advance.
