[2008.11619v3] On the power of Chatterjee rank correlation

Web24 de ago. de 2024 · The value of Pearson’s Correlation Coefficient can be between -1 to +1. 1 means that they are highly correlated and 0 means no correlation. -1 means that there is a negative correlation. Think of it as an inverse proportion. The t-test is a correlation coefficient testing for any correlation between two values. WebChatterjee (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 first proposed by Dette et al. (2013) that is zero if and only if the underlying pair of random variables is independent, but also is asymptotically normal … 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. eastbridge pca mt pleasant sc
