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
