Package dev.nm.stat.random.rng.univariate.gamma

Class InverseTransformSamplingGammaRNG

java.lang.Object

dev.nm.stat.random.rng.univariate.InverseTransformSampling

dev.nm.stat.random.rng.univariate.gamma.InverseTransformSamplingGammaRNG

All Implemented Interfaces:

RandomGammaGenerator, RandomNumberGenerator, Seedable

@Deprecated
public class InverseTransformSamplingGammaRNG
extends InverseTransformSampling
implements RandomGammaGenerator

Deprecated.

There exist much more efficient algorithms.

This is a pseudo random number generator that samples from the gamma distribution using the inverse transform sampling method. This method is very slow and much better methods exist.
