ChiSquare

public ChiSquare(long deg_freedom)

the seed is automatically provided by the SeedGenerator

Parameters:

deg_freedom - The degrees of freedom for the distribution

ChiSquare

public ChiSquare(long deg_freedom,
 long seed)

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

Parameters:
