Description

A function to compute cross-validation errors

Usage

Xvalid_all(
  mf,
  maxL,
  n.fold,
  minbucket,
  minsplit,
  cp,
  lookahead,
  sss,
  alpha.endcut,
  a,
  multi.start,
  n.starts
)

Arguments

mf	the data set with formula specified
maxL	the maximum number of splits
n.fold	the number of folds
minbucket	the minimum number of the studies in a terminal node
minsplit	the minimal number of studies in a parent node to be split
cp	the stopping rule for decrease of between-subgroups Q. Any split that does not decrease the between-subgroups Q is not attempted.
lookahead	an argument indicating whether to apply the "look-ahead" strategy when fitting the tree
