%description
The aim of the package is two-fold: (i) To implement the MMD method for
attribution of individuals to sources using the Hamming distance between
multilocus genotypes. (ii) To select informative genetic markers based on
information theory concepts (entropy, mutual information and redundancy).
The package implements the functions introduced by Perez-Reche, F. J.,
Rotariu, O., Lopes, B. S., Forbes, K. J. and Strachan, N. J. C. Mining
whole genome sequence data to efficiently attribute individuals to source
populations. Scientific Reports 10, 12124 (2020)
<doi:10.1038/s41598-020-68740-6>. See more details and examples in the
README file.
