%description
Computes 46 optimized distance and similarity measures for comparing
probability functions (Drost (2018) <doi:10.21105/joss.00765>). These
comparisons between probability functions have their foundations in a
broad range of scientific disciplines from mathematics to ecology. The aim
of this package is to provide a core framework for clustering,
classification, statistical inference, goodness-of-fit, non-parametric
statistics, information theory, and machine learning tasks that are based
on comparing univariate or multivariate probability functions.
