moezipfVariance {zipfextR}

Variance of the MOEZipf distribution.

Description

Computes the variance of the MOEZipf distribution for given values of \alpha and \beta.

Usage

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

Arguments

alpha

Value of the \alpha parameter (\alpha > 3).

beta

Value of the \beta parameter (\beta > 0).

tolerance

Tolerance used in the calculations. (default = 10^{-4})

Details

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

Value

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