st: sample selection in multinomial logit

[Andr� Paul <hcpats@hotmail.fr>]

Dear all

I would like to estimate the effect of firm size (and some other variables) 
on the outcome of a credit application (accepted, refused, withdrawn by the 
firm, still under examination), using a multinomial logit model.
I can observe the outcome for all firms (the data are exhaustive for a 
certain population), but I have only the firm data (i.e the explanatory 
variables) for limited liability companies, which, I guess, excludes a lot 
of small firms.
Could someone advise me which statistical method would be appropriated in 
this case and how to handle it with stata?

Thanks a lot,
Andre
