Rearrangement Correlation Coefficient
Description
The Rearrangement Correlation Coefficient is an adjusted version of Pearson's
correlation coefficient that accurately measures monotonic dependence
relationships, including both linear and nonlinear associations. This
method addresses the underestimation problem of classical correlation
coefficients in nonlinear monotonic scenarios through improved statistical
bounds derived from rearrangement inequalities. For more details,
see Ai (2024) .
