st: continuous variable+zip,zinb

[Johanna LEPEULE <lepeule@vet-nantes.fr>]

Dear Stata listers,

I use zip and zinb models.
I think I can use continuous variables in the inflate part (binary part) of 
the model if I check the linearity assumption between the continuous x 
variable and the Y variable. Is it right ?
However, I am not sure if I can use continuous variables in the Poisson or 
Negative binomial part.

Does anyone have suggestions ?
Thanks
Johanna Lepeule
