Zipf distribution probability density function (PDF).

Syntax
C#
Visual Basic
public static double ZipfPDF(int x, double s, int N);
Parameters
Parameters 
Description 
int x 
Function domain, positive integer or zero [0,N]. 
double s 
Distribution parameter, real positive value. 
int N 
Distribution parameter, positive integer. 
Returns

the Zipf distribution probability density function (PDF).

Remarks

Calculates the Zipf probability distribution function. The Zipf probability density function is defined by the following equation: 

 

where H(N,s) is a generalized Harmonic function, evaluated at parameters N,s and x,s respectively.
