public class Bootstrapping
extends AbstractBootstrapping

This operator constructs a bootstrapped sample from the given example set. That means that a sampling with replacement will be performed. The usual sample size is the number of original examples. This operator also offers the possibility to create the inverse example set, i.e. an example set containing all examples which are not part of the bootstrapped example set. This inverse example set might be used for a bootstrapped validation (together with an IteratingPerformanceAverage operator.
