Dear all,
I want to model bird distribution at see. The data consists 10000
samples but 90% are zeros. I try first a gamm (mgcv)with quasipoisson
but it might bee problematic with so many zeros. I look for a (spatial)
model that can use Zero Inflated Poisson distribution or similar. Is
there any?

Thank you
sincerely yours

Sven
