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
