jhpro.stat.MomentsFac

public class MomentsFac
extends java.lang.Object

Calculations of factorial moments of a distribution. The factorial moments are calculated as up to the order n, where n is the oder of the moment. The factorial moments are defined as F_1= (1st order), F_2= (second order), F_2= (3rd order) and so on. The code works only for integer random variables. Statistical errors are also evaluated.

MomentsFac

public MomentsFac(int order)

Initialization of the factorial moments.

Parameters:

order - Max oder of the factorial moment

Method Detail

process

public void process(int n)

Process current event for an integer random variable
