Residuals From a Fitted Rpart Object
Usage
residuals.rpart(object, type)
Arguments
object
|
fitted model object of class rpart . This is assumed to be the result
of some function that produces an object with the same named
components as that returned by the rpart function.
|
type
|
Indicates method of residual for a classification tree (no distinction
is made for methods "anova" , "poisson" , or "exp" ). Allows the
following types of residuals: "usual" (misclassification errors),
"pearson" (sum of the observed minus fitted squared over fitted), and
"deviance" (minus twice logarithm of fitted).
|
Value
vector of residuals of type type
from a fitted rpart
object.Examples
data(solder)
fit <- rpart(skips ~ Opening + Solder + Mask + PadType + Panel,
data=solder, method='anova')
plot(fitted(fit),residuals(fit))
