I think it is about the same.

I noticed that Dale showed how to fit a zero-inflated gamma model in NLMIXED
a while back:
It seems to me that the zero-inflated gamma model in the link above could be
thought of as a hurdle gamma model, since the zeros are generated from a
binary process while the non-zero responses follow a gamma process.
Is my thinking off here?
