Hi all

I'm having a problem running -truncreg-.  I have a dataset with 10675 obs with
truncation at zero.
After entering the -truncreg- command:

-truncreg  super_contrib99doll p11 age age_sqr marriage gender famsize

I receive the following:

(note: 4679 obs. truncated)

Fitting full model:

initial values not feasible

I don't have this problem if I run the regression with a subsample of about
3500 obs.
Any suggestions, please?
