%description
The nonparametric methods for estimating copula entropy, transfer entropy,
and the statistics for multivariate normality test and two-sample test are
implemented. The methods for estimating transfer entropy and the
statistics for multivariate normality test and two-sample test are based
on the method for estimating copula entropy. The method for change point
detection with copula entropy based two-sample test is also implemented.
