residuals.arbor
Residuals from an Arbor Object

### Description

Returns a vector of residuals from an arbor object.

### Usage

    residuals.arbor(object, type = c("usual", "pearson", "deviance"))

### Arguments

object | a fitted model object of class arbor. This model is assumed to be the result of a function that produces an object with the same named components as that returned by the arbor function.
type | indicates a method of residual for a classification tree. (No distinction is made for methods "anova", "poisson", or "exp".) Can be one of the following types of residuals. "usual": misclassification errors. "pearson": the sum of the observed minus fitted squared over fitted. "deviance": minus twice logarithm of fitted.

Value
returns a vector of residuals of type type from a fitted arbor object.
Examples

    library("arbor")
    data(solder, package = "Sdatasets")
    fit <- arbor(skips ~ Opening + Solder + Mask + PadType + Panel,
           data = solder, method = 'anova')
    pr <- data.frame(predict(fit), residuals(fit))
    pr[880:900,]
