r-cran-energy - 1.7-11-1 main

The energy package implements 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.
