Generalized additive model (source code)

= Generalized additive model

A generalized additive model has <linear predictor> $g(\mu_i)=\alpha+\sum_j s_j(x_{ij})$. Centering the smooth functions identifies the intercept. The response family and <link function> remain part of the model; an unspecified software family must not be inferred from the response name.
