报告摘要：In this talk I will revisit two earlier papers of mine on minimax-optimal high-dimensional independence testing using rank correlations. The test statistics are rank-based, of a maximum-type, and valid when both the dimension and sample size increase to infinity. The proof is based on U-statistics theory, Stein's method, Zaitsev's Gaussian approximation theory, and minimax arguments.
