zipfpoylogVariance {zipfextR}R Documentation

Variance of the ZipfPolylog distribution.

Description

Computes the variance of the ZipfPolylog distribution for given values of α\alpha and β\beta.

Usage

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

Arguments

alpha

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

beta

Value of the β\beta parameter (β(,+)\beta \in (-\infty, +\infty)).

tolerance

Tolerance used in the calculations. (default = 10410^{-4})

Details

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

Value

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