Maximum Likelihood Estimation for q-Exponential (Tsallis) Distributions

Abstract

This expository note describes how to apply the method of maximum likelihood to estimate the parameters of the ``$q$-exponential'' distributions introduced by Tsallis and collaborators. It also describes the relationship of these distributions to the classical Pareto distributions.
