public class MomentsFacNormextends ObjectCalculations of normalized factorial moments of a distribution. The normalised factorial moments are calculated as up to an orbitrary order n, where n is the oder of the moment. The factorial moments are defined as
F_1=1 (1st order),
/ ^2 (second order),
/N^3 (3rd order)
and so on. The general form is F_q=
/ ^q, where N^[q]=N*(N-1)*..(N-q+1). The code works only for integer random variables. Statistical errors are also evaluated. If they are set to 0, this means that there is no enough events for their calculation.
