The function calculates Shannon's Entropy. The function is meant for internal use only. To calculate the entropy for each action in the design, please use the wrapper function calculate_entropy

calc_entropy(design, priors = NULL)

## Arguments

design A matrix with rows equal to the number of rules and columns equal to the number of actions or a list of such matrices. 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.

## Value

Returns a vector of entropies for each possible action with the following attributes:

1. design

2. priors

3. pr_aj_rk

4. pr_rk_aj
