Hi Statalisters,

I used the -gologit2- command to estimate two generalized ordered
logit models with the same variable but in two different years. Then,
I ran the -mfx2- command to get the marginal effects of each one. Now,
I want to compare statisticaly if there exist differences between the
marginal effects of each variable on this models. Can I do that? If
yes, How?

I wrote both commands, and darned if I know how. My guess is that if it can be done with mlogit or ologit then the same approach would work with gologit2. May Boggess answered a similar question in 2004, so maybe you can figure out how to adapt her advice if nobody has anything simpler:

As a sidelight, for commands it supports (which include gologit2), -margeff- is faster and more powerful than -mfx2-. You can get -margeff- from SSC.
