WebbAbstract A framework is presented for generalized additive modelling under shape constraints on the component functions of the linear predictor of the GAM. We represent shape constrained model components by mildly non-linear extensions of P-splines. WebbThe model it concerns is very similar to (3): y i = β 0 + J ∑ j=1 β jX ji +f(X ai,X bi)+u i. (8) This model is linear in X 1 through X J, fully nonparametric in Xa and X b, and additive …
