[Limdep Nlogit List] Another selection qeustion-with censored model

[Martin Chun Qiu]

Dear Limdepers:

I am also estimating a selection problem where the first equation is a standard probit on z. In the second equation, the dependent variable y is censored by x. The presence of x is determined by z. If z=1, x is present and y is censored. If z=0, x is absent and y is not censored. Any thoughts to handle model like this?  

Warm regards,
