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. |
the Zipf distribution cumulative distribution function (CDF).
Calculates the Zipf cumulative density 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 N,s-1 respectively.
