jensen_shannon_divergence {statcomp}

Generalized disequilibrium measure for ordinal pattern distributions based on the Jensen-Shannon Divergence

Description

Computes a normalized form of the Jensen-Shannon Divergence

Usage

jensen_shannon_divergence(p, q="unif")

Arguments

p

An ordinal pattern distribution

q

A second ordinal pattern distribution to compare against p, or a character vector q="unif" (comparison of p to uniform distribution)

Details

This function returns a distance measure.

Value

A vector of length 1.
