Hi there,

I am predicting animal presence in a grid using a binomial 
distribution and the package mgcv. My data has many many zeros, is 
there a way to consider this and counterbalance it in R. The results 
I get are probabilities of less than 0.5 and I believe the zero 
inflated dataset is affecting it. I am already using a weight in my 
model with the effort spent in each grid cell.

Thanks for your feedback, with my best regards,

Simone
