[R] Nonliner Rgression using Neural Nnetworks

2003-07-11 Thread Yukihiro Ishii
Hi, I am an old hand at chemistry but a complete beginner at statistics including R computations. My question is whether you can carry out nonlinear multivariate regression analysis in R using neural networks, where the output variable can range from -Inf to + Inf., unlike discr
