gam uses the backfitting algorithm to combine different smoothing or fitting methods. The methods currently supported are local regression and smoothing splines
procedure we call the local scoring algorithm. The technique is applicable to any likelihood-based regression model: the class of generalized linear models.
One task among others in a regression analysis is to find the right transformation on the predictors. Additive models can help here. Let's fit an additive model
The local scoring algorithm is analogous to the iterative reweighted least squares algorithm for solving likelihood and nonlinear regression equations. At each
