Are you working with parametric (your title) or non-parametric (your
text) data? And what type of data (time series?)? Finally what kind of
non-linearities are you interested in?
Non-linear regression models (threshold autoregression, smooth
transition, ANN) are avalaible in package tsDyn, the multivariate
extension is not currently avalaible on CRAN but is pretty ready. Let me
know if this is the type of functions you are interested in.
