For a multinomial *logit* model, I'd rather advice Marc Gurgand's -semlog-

Betreff: st: Heckman multinomial logit model

I would like to do an extension of Heckman.

First, I have a multinomial logit model of the form:
Yi=Zi g+ui
where Yi= 0,1 or 2 (selection equation).

Second, I have a general equation of the form
Wj=Xj b+vj (regression equation).

1) How can I get maximum likelihood estimates from the selection equation?
2) Howcan I create Mills ratio from these estimates?
3) How can I do the regression equation with the Mills ratio?

Thanks
