Class MomentsFac
java.lang.Object
jhpro.stat.MomentsFac
public class MomentsFac
- extends 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.
