st: Population-Averaged Probit

[Claude Francoeur <claude.francoeur@hec.ca>]

Hello,

What would be the command to generate a pseudo R-squared (or McFadden 
R-squared) for a Population-Averaged Probit?

I would also need the repartition between "zeros" and "ones" that are 
actually used in the regression. My data file contains 781 observations, but 
Stata only uses 581 in the regression.

Thanks,

Claude
