The function calculates the probability of a rule conditional on observing a given action and is part of calculating the entropy of an action. This probability is also referred to as the posterior probability. The function is meant for internal use only.
A matrix with the probabilities of actions conditional on a given rule.
A vector of prior values. If the design is a list of matrices, priors can be a matrix with rows equal to the length of the design and columns equal to the number of rules.
An r x a matrix of probabilities
