WebEstablishing limiting distributions of Chatterjee’s rank correlation for a general, possibly non-independent, pair of random variables has been eagerly awaited to many. This paper shows that (a) Chatterjee’s rank correlation is asymptotically normal as long as one variable is not a measurable function of the other, and (b) the corresponding asymptotic … Web27 de abr. de 2024 · Chatterjee [38] proposed a simple correlation coefficient (CODEC) base on (13).
