residuals.rpart {rpart} | R Documentation |
residuals.rpart(object, type)
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).
