Web26 de ago. de 2024 · Chatterjee (2024) introduced a simple new rank correlation coefficient that has attracted much recent attention. The coefficient has the unusual appeal that it not only estimates a population quantity that is zero if and only if the underlying pair of random variables is independent, but also is asymptotically normal under independence. … 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 …

WebChatterjee’s rank correlation coefﬁcient is in fact rate-suboptimal against the two local alterna-tive families under consideration; recall point (iii) above.

As a lay person I'm having trouble understanding how Chatterjee's formula as defined produces a correlation between two time series when it only references one of them. Pearson's/Spearman's correlations both reference the separate series ( X, Y), but this one doesn't. Let r i be the rank of Y ( i), that is, the number of j such that Y ( j ...
