In dad: Three-Way / Multigroup Data Analysis Through Densities

Matrix of divergences between discrete probability densities given the probabilities on their common support

Description

Computes the matrix of the Jensen-Shannon divergences between several multivariate or univariate discrete probability distributions on the same support (which can be a Cartesian product of q sets), given the probabilities of the states (which are q-tuples) of the support.

Usage

matddjensenpar(freq)

Arguments

freq	list of arrays. Their dim attribute is a vector with length q, its elements containing the numbers of levels of the sets. Each array contains the probabilities of the discrete distribution on the same support.

Value

Positive symmetric matrix whose order is equal to the number of densities, consisting of the pairwise Jensen-Shannon divergences between the discrete probability densities.
