... 14.6 Nonparametric or Rank Correlation It is precisely the uncertainty in interpreting the significance of the linear correlation coefficient r that leads us to the important concepts of nonparametric or rank correlation. As before, we are given N pairs of measurements (xi , yi ). Before, difficulti ...
