Have you considered 'glm(... family=poisson)'? Hope this helps. Spencer Graves

I am currently running a script in S-PLUS 2000 on a Windows platform
using the canned S-PLUS nonlinear regression function nls. I was
wondering if anyone on the list has had any experience creating their
own nonlinear regression function using something other than least
squares? I am particularly interested in utilizing a Poisson family in
my calculations.

Thanks,
