Constructor Details

Cauchy

public Cauchy(double median,
 double scale)

the seed is automatically provided by the SeedGenerator

Parameters:

median - The median of the distribution

scale - The scale of the distribution

Cauchy

public Cauchy(double median,
 double scale,
 long seed)

The constructor with which a specific seed is set for the random number generator

Parameters:

median - The median of the distribution

scale - The scale of the distribution

seed - The initial seed for the generator, two instances with the same seed will generate the same sequence of numbers

Method Details

sample

public double sample()

Generate a new random number.

Specified by:

sample in interface ContinuousGenerator

Returns:

The next random number in the sequence
