Rafa needs to specify which response outcome he would like marginal
effects of, as follows:
svymlogit occ schooling experience region, b(1)
mfx compute, predict(p outcome(3)) nose
Usually when you don't specify the -predict- option in -mfx-, it just
uses the default -predict- option for the estimation command you are
following. But -mlogit- is unusual in that it doesn't have a default
predict option. Try the following:
clear
sysuse auto
mlogit rep for
predict p
and you will get the same type of message that Rafa did.
