Hi,

I am running a multinational logistic regression with the mlogit command. I have noticed that the coefficient of one of the independent variables (a dummy) takes a negative sign, which i interpret as the dummy having a negative impact on the probability of (let's say) outcome 1 with reference to the base outcome.

but when I estimate the marginal effects as follows:

Code:
margins x, post pr (out(1))
I get the opposite result, that is, a change from 0 to 1 in the independent variable has a positive impact on the probability of outcome 1.

Can someone explain to me why that could happen?

Thanks!

Amy
