The R package tseriesEntropy
implements an entropy measure of
dependence based on the Bhattacharya-Hellinger-Matusita distance. It can
be used as a (nonlinear) autocorrelation/crosscorrelation function for
continuous and categorical time series. The package includes tests for
serial and cross dependence and nonlinearity based on it. Some routines
have a parallel version that can be used in a multicore/cluster
environment. The package makes use of S4 classes.
