residuals.earth: Residuals for an earth model

Description

Residuals of an earth model.

Usage

"residuals"(object = stop("no 'object' argument"), type = NULL, warn = TRUE, ...)

Arguments

object

An earth object. This is the only required argument.

type

One of "earth" (default) Residuals (from the lm fit on bx). "standardize" Residuals divided by se * sqrt(1 - h_ii). See the standardize argument of plot.earth. "delever" Residuals divided by sqrt(1 - h_ii). See the delever argument of plot.earth. "deviance" Residuals as above, unless the object has a glm component, in which case return the glm deviance residuals. "glm.pearson" "glm.working" "glm.response" "glm.partial" Return the corresponding glm residuals (from the glm fit on bx). Can be used only if the earth model has a glm component.

warn

This function gives warnings when the results are not what you may expect. Use warn=FALSE to turn of just these warnings.

...

Unused, but provided for generic/method consistency.

Value

The residual values (will be a matrix for multiple response models).

Examples

data(etitanic)
earth.mod <- earth(pclass ~ ., data=etitanic, glm=list(family=binomial))
head(resid(earth.mod, warn=FALSE))      # earth residuals, a column for each response
head(resid(earth.mod, type="earth"))    # same
head(resid(earth.mod, type="deviance")) # GLM deviance residuals, a column for each response
