A new coefficient of correlation
S Chatterjee - Journal of the American Statistical Association, 2021 - Taylor & Francis
Is it possible to define a coefficient of correlation which is (a) as simple as the classical
coefficients like Pearson's correlation or Spearman's correlation, and yet (b) consistently …
