Dear all, i estimated a mlogit with 8 outcomes, which reject the IIA assumtion tested with a hsiao test: mlogtest, sm i would be pleased to get the marginal effects of my model. If i run the command to obtain, for instance, the marginal effects for outcome 1: mfx compute, predict(outcome(1)) i obtain very suspects results, namely mfx with signs and sign completely different from the ones of the coefs estimates. I use Stata 12, and from the manuals mfx might compute the marginal effect like in the previous stata versions. Do you know if something changed? Thanks

A few side points first:
