Dear all,
I'am using mlogit to test IIA hypothesis. I'get the test statistique who is
negative, a p-value of 1, and a text saying that the IIA hypothesis is rejeted.
Does a negative value mean that constraint model is more efficient that that
the full model ? what to do in this case ?
Sincerly
Hi, you should look at hmftest in mlogit package. However, be cautious
when you use IIA test, it is not very reliable as Long and Freese
(2006:243) have shown.
