Abstract

In a recent PRL (2013, 111, 180604), we invoked the Shore and Johnson axioms which demonstrate that the least-biased way to infer probability distributions fpig from data is to maximize the Boltzmann-Gibbs entropy. We then showed which biases are introduced in models obtained by maximizing nonadditive entropies. A rebuttal of our work appears in entropy (2015, 17, 2853) and argues that the Shore and Johnson axioms are inapplicable to a wide class of complex systems. Here we highlight the errors in this reasoning.

  • Tsallis asserts that “We see that the SJ set of axioms, demanding, as they do, system independence, are not applicable unless we have indisputable reasons to believe that the data that we are facing correspond to a case belonging to the exponential class, and by no means correspond to strongly correlated cases such as those belonging to the power-law or stretched-exponential classes, or even others”

Summary

Introduction

In a recent PRL (2013, 111, 180604), we invoked the Shore and Johnson axioms which demonstrate that the least-biased way to infer probability distributions {pi } from data is to maximize the Boltzmann-Gibbs entropy. I (or any function that is monotonic with this entropy), under constraints where qi is the prior distribution on pi that contains any foreknowledge of the system.
