Class NMDistribution

java.lang.Object

javanpst.distributions.tests.NMDistribution

public class NMDistribution
extends java.lang.Object

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

Method Summary

Modifier and Type	Method and Description
double	computeLeftProbability(int n, double realNM) Computes left tail p-value of the NM distribution.
double	computeRightProbability(int n, double realNM) Computes right tail p-value of the NM distribution.
static NMDistribution	getInstance() Singleton pattern access to the distribution
static Incomplete2KeyTable	getTableLeft() Gets the table of the left tail of the distribution
static Incomplete2KeyTable	getTableRight() Gets the table of the right tail of the distribution
boolean	isApproximate() Tests if the last estimation was approximate
