Looks useful, @rafaqz! From a brief glance at their supplementary information, this looks pretty straight forward to implement.

One parameter in their method is T, the fraction of pairwise distances considered. They say "Rougher signals require a larger fraction of pairwise distances to be considered because their ranks are less tightly coupled". To determine roughness, they use a measure involving the standard deviation. We should be maximally flexible, so we should implement a dispatch-based method for allowing not only standard deviation but other measures of "data spread" when calculating T.
