Dear helper,

I am working with a nnet using large data set (23K) and have some questions. I have a binary response (occurrence & non-occurrence of event) with 8 predictors.

(1) How can I reproduce plot in Hastie et al. (page 141), i.e. natural
cubic splines of tensor product?
(2) How does nnet treat the response. It seems that by default it
treats Y as numeric (?). Can I change the response as factor? or, does it matter?

Thank you,

Ilham
