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.
