WebThis paper compares Chatterjee’s new correlation coefficient with three established rank correlations that also facilitate consistent tests of independence, namely Hoeffding’s , Blum–Kiefer–Rosenblatt’s , and Bergsma–Dassios–Yanagimoto’s . We compare the computational efficiency of these rank correlation coefficients in light of ...

Did you know?
WebChatterjee (2024)'s ingenious approach to estimating a measure of dependence first proposed by Dette et al. (2013) based on simple rank statistics has quickly caught attention. This measure of dependence has the unusual property of being between 0 and 1, and being 0 or 1 if and only if the corresponding pair of random variables is independent or one is a … Web2 de abr. de 2024 · 4. 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 ...

Think of it as an inverse proportion. The t-test is a correlation coefficient testing for any correlation between two values.
WebChatterjee’s rank correlation coefficient is in fact rate-suboptimal against the two local alterna-tive families under consideration; recall point (iii) above. Our theoretical analysis thus echos Chatterjee’s empirical observation that his test of independence can suffer from low power; see Remark 7 below.
