SymKL.Plugin: SymKL.Plugin

In EntropyEstimation: Estimation of Entropy and Related Quantities

Description

Returns the augmented plugin estimator of Symetrized Kullback-Leibler Divergence. See Zhang and Grabchak (2014b) for details.

Usage

Arguments

x	Vector of counts from first distribution. Must be integer valued. Each entry represents the number of observations of a distinct letter.
y	Vector of counts from second distribution. Must be integer valued. Each entry represents the number of observations of a distinct letter.
