regPath.SDTree: Calculate the regularization path of an SDTree

Description

This function calculates the variable importance of an SDTree for different complexity parameters.

Usage

# S3 method for SDTree
regPath(object, cp_seq = NULL, ...)

Value

An object of class paths containing

cp

The sequence of complexity parameters.

varImp_path

A matrix with the variable importance for each complexity parameter.

type

Path type

Arguments

object

an SDTree object

cp_seq

A sequence of complexity parameters. If NULL, the sequence is calculated automatically using only relevant values.

...

Further arguments passed to or from other methods.
