gam and of class
"gam" inheriting from classes "glm" and "lm". Method
functions anova, logLik, influence, plot,
predict, print, residuals and summary exist for
this class.All compulsory elements of "glm" and "lm" objects are present,
but the fitting method for a GAM is different to a linear model or GLM, so
that the elements relating to the QR decomposition of the model matrix are
absent.
gam object has the following elements:A Key Reference on this implementation:
