%description
E-statistics (energy) tests and statistics for multivariate and univariate
inference, including distance correlation, one-sample, two-sample, and
multi-sample tests for comparing multivariate distributions, are
implemented. Measuring and testing multivariate independence based on
distance correlation, partial distance correlation, multivariate
goodness-of-fit tests, k-groups and hierarchical clustering based on
energy distance, testing for multivariate normality, distance components
(disco) for non-parametric analysis of structured data, and other energy
statistics/methods are implemented.
