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
