Class TotalNumberOfRunsDistribution

java.lang.Object

javanpst.distributions.tests.TotalNumberOfRunsDistribution

public class TotalNumberOfRunsDistribution
extends java.lang.Object

An implementation of the Total number of runs test distribution. Uses a Singleton pattern to ensure only an instance of the class is allowed.
