energy: E-statistics (energy statistics)

E-statistics (energy) tests and statistics for comparing distributions: multivariate normality, multivariate distance components and k-sample test for equal distributions, hierarchical clustering by e-distances, multivariate independence tests, distance correlation, goodness-of-fit tests. Energy- statistics concept based on a generalization of Newton's potential energy is due to Gabor J. Szekely.
