Query: A rapid algorithm to calculate joint probability matrices for joint
  entropies of arbitrary order   There is no closed form analytical equation or quick method to calculate
probabilities based only on the entropy of a signal or process. Except in the
cases where there are constraints on the state probabilities, one must
typically derive the underlying probabilities through search algorithms. These
become more computationally expensive as entropies of higher orders are
investigated. In this paper, a method to calculate a joint probability matrix
based on the entropy for any order is elaborated. With this method, only first
order entropies need to be successfully calculated while the others are derived
via multiplicative cascades.
