%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) <doi:10.52202/079017-1180>.
