isDiscrete

Attempts to determine if the input data is from a discrete distribution. Will
return true if the data type is of type integer or there are non-unique
values.

Computes the t* statistic corresponding to the tau* population
coefficient introduced by Bergsma and Dassios (2014) <DOI:10.3150/13-BEJ514>
and does so in O(n^2) time following the algorithm of Heller and
Heller (2016) <DOI:10.48550/arXiv.1605.08732> building off of the work of Weihs,
Drton, and Leung (2016) <DOI:10.1007/s00180-015-0639-x>. Also allows for
independence testing using the asymptotic distribution of t* as described by
Nandy, Weihs, and Drton (2016) <DOI:10.1214/16-EJS1166>.
