Web3 de dez. de 2024 · In the present paper, we propose a direct and simple extension of Azadkia & Chatterjee's rank correlation T introduced in [4] to a set of q ≥ 1 endogenous variables where me make use of the fact that T characterizes conditional independence. WebMoreover, we establish the optimal efficiency in the statistical sense of both tests. In addition, we also investigate the power of a simple consistent rank correlation coefficient recently proposed by Chatterjee (2024) against local alternatives. Our results show that Chatterjee’s coefficient is unfortunately statistically inefficient.
