Estatistics (energy statistics)
Research and software related to Estatistics
Estatistics (energy statistics) refers to a class of tests and statistics
based on Euclidean distances. Applications include testing
multivariate normality, multivariate distance components and
ksample test for equal distributions, hierarchical clustering by edistances,
multivariate independence tests, distance correlation, goodnessoffit tests.
