[Limdep Nlogit List] (no subject)

[Angelo Zago]

HI all
I am estimating a sample selection model where in the structural equation I 
have performance at university and then I have an equation for the 
participation at University.
What is different from the usual setup, e.g., the standard wage equation 
estimation, however, is that some of those observations who do participate 
may still get a zero in the structural equation (since low performance 
values are not reported).
Is Tobit with selection in Limdep appropriate or is there something more 
appropriate available?
Thanks for any suggestion
Sincerely
A. Zago
