摘要：In this talk, we relax the commonly imposed dependence conditions that seem to be the standard assumption in high-dimension. With the relaxed conditions, the scope of applicability of the results in Chen and Qin (2010) broadens. Then the application to a fully nonparametric rank-based comparison of high-dimensional populations is given.  To develop the theory, we prove a novel result for studying the asymptotic behavior of quadratic forms in ranks. Simulation study shows that the developed rank-based method performs comparably well with mean-based methods. It has significantly superior power for heavy tailed distribution. The application to an EEG data with the objective of examining association between alcohol use and change in brain function is given.
