Class InverseTransformSamplingGammaRng

java.lang.Object

com.numericalmethod.suanshu.stats.random.univariate.InverseTransformSampling

com.numericalmethod.suanshu.stats.random.univariate.gamma.InverseTransformSamplingGammaRng

All Implemented Interfaces:

RandomGammaGenerator, RandomNumberGenerator, java.io.Serializable

Deprecated.

There exist much more efficient algorithms.

@Deprecated
public class InverseTransformSamplingGammaRng
extends InverseTransformSampling
implements RandomGammaGenerator

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.
