sampleRankCorrelation

sampleRankCorrelation(x, y): number

Defined in: src/sample_rank_correlation.js:53

The rank correlation is a measure of the strength of monotonic relationship between two arrays

Tied values share the average of the ranks they span, so the result depends only on the paired data and not on the order the pairs are given in. When either input has no rank variance the correlation is undefined and the result is NaN.
