Hey folks,

I'm trying to do all subsets on a zero-inflated poisson regression.  I'm aware of the leaps and regsubsets functions but I don't know if they work for ZIP regressions or how the syntax fits in for them.  Can anyone help?
The model syntax is:
> zip.zc <- zicounts(resp=Scars~.,x=~Location + Lar + Mass + Lac + Lar:Mass + Location:Mass, data = alan2, distr="ZIP")

Many thanks
