Description

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

Usage

1
zipfpoylogVariance(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.
