You can only sent plain text and no attachments to
the statalist, so your message got hopelessly
garbled. So I can't answer you question directly,
I can only give you some literature recomendations:
James W. Hardin and Joseph M. Hilbe "Generalized
Linear Models and Extensions, second edition.
College Station, TX: Stata Press.
