Class PageDistribution

java.lang.Object

javanpst.distributions.tests.PageDistribution

public class PageDistribution
extends java.lang.Object

An implementation of the Page distribution. Uses a Singleton pattern to ensure only an instance of the class is allowed.

Method Summary

Modifier and Type	Method and Description
double	computeAsymptoticProbability(int n, int k, double L) Computes asymptotic p-value of the Page distribution.
double	computeExactProbability(int n, int k, double L) Computes Exact p-value of the Page distribution.
static PageDistribution	getInstance() Singleton pattern access to the distribution
static Critical2KeyTable	getTable() Gets the table of critical values of the distribution
