All Implemented Interfaces:

ConfigurationListener

public class AnovaSignificanceTestOperator
extends SignificanceTestOperator

Determines if the null hypothesis (all actual mean values are the same) holds for the input performance vectors. This operator uses an ANalysis Of VAriances approach to determine probability that the null hypothesis is wrong.
