Constructor Detail

Gamma

public Gamma(double scale,
             double shape)

the seed is automatically provided by the SeedGenerator

Parameters:

scale - The scale of the distribution : scale > 0

shape - The shape of the distribution : shape > 0

Gamma

public Gamma(double scale,
             double shape,
             long seed)

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

Parameters:

scale - The scale of the distribution : scale > 0

shape - The shape of the distribution : shape > 0

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