WebbDescription A constrained generalized additive model is ﬁtted by the cgam routine. Given a set of pre-dictors, each of which may have a shape or order restrictions, the maximum likelihood estima-tor for the constrained generalized additive model is found using an iteratively re-weighted cone projection algorithm.
