zipfpeVariance: Variance of the Zipf-PE distribution.

In zipfextR: Zipf Extended Distributions

Description

Computes the variance of the Zipf-PE distribution for given values of α and β.

Usage

zipfpeVariance(alpha, beta, tolerance = 10^(-4))

Arguments

alpha	Value of the α parameter (α > 3).
beta	Value of the β parameter (β \in (-∞, +∞)).
tolerance	Tolerance used in the calculations. (default = 10^{-4})

Details

The variance of the distribution only exists for α strictly greater than 3.

Value

A positive real value corresponding to the variance of the distribution.
