fitcgam to fit a generalized additive model for binary classification.
A generalized additive model (GAM) is an interpretable model that explains class scores
(the logit of class probabilities) using a sum of univariate and bivariate shape functions of
fitcgam uses a boosted tree as a shape function for each
predictor and, optionally, each pair of predictors; therefore, the function can capture a
nonlinear relation between a predictor and the response variable. Because contributions of
individual shape functions to the prediction (classification score) are well separated, the
model is easy to interpret.
