Method Details
-
apply
double[] apply(double[] data) Performs a rank transformation on the input data, returning an array of ranks.
Ranks should be 1-based: the smallest value returned in an array of ranks should be greater than or equal to one, rather than 0. Ranks should in general take integer values, though implementations may return averages or other floating point values to resolve ties in the input data.
