st: sample selection bias

["Kenya Valeria Micaela de Souza Noronha" <kenya@cedeplar.ufmg.br>]

Dear all

I need to estimate a model based on heckman method, but the selectivity is 
modelled as a multinomial logit. Is there any command in Stata for this 
model? How can i estimate it?

thanks

Kenya
