Detailed Description

Zeta Distributed Distributed Random Variable

ZetaVariable defines a discrete random variable with Zeta distribution.

The Zeta distribution is closely related to Zipf distribution when N goes to infinity.

Zeta distribution has one parameter, alpha, $\alpha > 1$ (real). Probability Mass Function is $f(k; \alpha) = k^{-\alpha}/\zeta(\alpha)$ where $\zeta(\alpha)$ is the Riemann zeta function ( $\sum_{n=1}^\infty n^{-\alpha} )$
