public class Bernoulli
extends Generator
This class implements a random generator with a Bernoulli distribution. It uses the standard random engine of java java.util.Random as basis.

Random, Generator

Constructor Index

o Bernoulli(double)
Creates a new Bernoulli-distributed generator using the current time as seed and the given success probability to model the distribution.
o Bernoulli(long, double)
Creates a new Bernoulli-distributed generator using the given seed to initialize it and the given success probability to model it.
o Bernoulli(RandomEngine, double)
Creates a new Bernoulli-distributed generator using the given pseudo-random engine and the given success probability to model the distribution.

Method Index

o density(double)
Returns the value of the density in the given point.
o draw()
Draws a boolean value according to the Bernoulli distribution.
o setParam(double)
Sets a different parameter for this generator.
o type()
Returns the type of the extracted value.
