Hi to all, I'd like to check my cozigam model with a continuous response. If I only had a GAM I could do gam.check(b), but with cozigam I'm not getting a way to check for residuals, fitted values, qq plot.. Even if I have to do it separately for zeros and non-zeros part, how can I assure that the family (and/or the data transformation) I chose is the best one? Does anyone knows how to do it? thanks a lot, barbara [[alternative HTML version deleted]]
