Manuel,

us your margeff updated?

You write..."His suggestion is to use the following command:
> Margeff, dummies (B *)
> where D are all dummies for which you want to calculate the marginal
> effects."

are dummies B or D?

I'm using margeff after ologit and it works fine. Try to write the
name of your dummies.

ologit vardep vars
margeff, at (mean) dummies(name_dummy1)

Best

Joao Lima
