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.
