Residuals From a Fitted Arbor Object

USAGE:

residuals.arbor(object, type) 

REQUIRED ARGUMENTS:

object
fitted model object of class arbor. This is assumed to be the result of some function that produces an object with the same named components as that returned by the arbor function.

OPTIONAL ARGUMENTS:

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 arbor object.

EXAMPLES:

fit <- arbor(skips ~ Opening + Solder + Mask + PadType + Panel, 
       data=solder, method='anova') 
plot(predict(fit),residuals(fit))
