residuals.gamViz: Generalized Additive Model residuals

In mgcViz: Visualisations for Generalized Additive Models

Generalized Additive Model residuals

Description

Extension of mgcv::residuals.gam. Returns residuals for a fitted GAM model object. Pearson, deviance, working and response residuals are available as in the method from mgcv, but this version also provides residual types "tunif" and "tnormal". The former are obtained using the cdf of the response distribution (if available). The latter are obtained by further transforming the uniform residuals using the quantile function (i.e. the inverse cdf) of a standard normal variable.

Usage

## S3 method for class 'gamViz'
residuals(object, type = "deviance", ...)

Arguments

object	an object of class gamViz, the output of a getViz() call.
type	the type of residuals wanted. If should be one of "deviance", "pearson", "scaled.pearson", "working", "response", "tunif" or "tnormal". Not all are available for each family.
...	further arguments passed to mgcv::residuals.gam.
