Abstract
Several useful plots for generalized linear models (GLMs) can be applied to generalized additive models (GAMs) with little modification. A plot for a GLM using the estimated sufficient predictor can be extended to a GAM by replacing the ESP by the estimated additive predictor . The residual plot, response plot, and transformation plots are examples. Since a GLM is a special case of a GAM, a plot of EAP versus ESP is useful for checking goodness of fit of the GLM.
