Re: st: Trouble with maxcnt command as part of prvalue calculations

Dr. Williams --

Thank you very much for your comments.

Desperate is a bit dramatic, but pretty close to accurate.

I am a bit of a novice at Stata, so new code is a challenge, to say the least.

Do you have a suggestion for an alternative to prvalue?
Again, I have a ZINB model with a DV of 0 to 95.

I find the max of 30 flummoxing as well.
