Hi Everyone,

I am trying to estimate truncated regression using the method offered by
Bloom and Killingsworth (1985). This method is used instead of the
conventional one, when part of the dependent variable (the ones =0) of
probit equation do not exist. This estimation method is not availabe with
stata. as far as I have checked it is available only with TSP 5.0, which I
can not find in short time.

My question is, is there anyone who developed a module in stat for the
Bloom and Killingsworth (1985) procedure for truncated regression, where
the selection variable for dependent variable is partially not observed.

Thank you very much

by a latent truncation variable. Journal of Econometrics 27, 131? 135.

the method is for instance used by:

and the start-up size of new technology-based firms, International Journal
of Industrial Organization, 22  1183? 1211.
