st: [Stata 9]: Bug in ivprobit, twostep?

[Arif Mamun <aalmamun@u.washington.edu>]

Hi,

In Stata 9, I am trying to implement ivprobit, twostep with the option 
"first". But the output doesn't provide any report of the first stage 
regression. Any idea about why this is happening?

On a related note, does the ivprobit, mle model take much longer to 
implement? In fact, I waited for couple of hours without luck for a 
specification that ran in a few minutes with the two-step model.

Thanking you in anticipation,

Arif.
