Constructor Details

FDistribution

public FDistribution(long num_deg_freedom,
 long den_deg_freedom)

the seed is automatically provided by the SeedGenerator

Parameters:

num_deg_freedom - The numerator degrees of freedom for the distribution

den_deg_freedom - The denominator degrees of freedom for the distribution

FDistribution

public FDistribution(long num_deg_freedom,
 long den_deg_freedom,
 long seed)

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

Parameters:

num_deg_freedom - The numerator degrees of freedom for the distribution

den_deg_freedom - The denominator degrees of freedom for 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
