Dear list members, 

I am estimating a -probit-/-logit- model and my question is
about its comparison with the linear probability model
(simple OLS).  

When I run the -probit- or -logit-, the number of
observations is the same but much less when compared with
the OLS estimation of the very same model!  (E.g., the no.
of obs. in my probit and logit estimate is 12,000 while
it's only 10,000 in the OLS regression.)

Could anyone please tell me why do -probit- and -logit-
drop these observations?

Thank you very much,

Nishant
