    The problem of testing for high-dimensional distributions between two treatments is considered. The two-sample tests on high-dimensional variance-covariances are proposed without imposing the normality assumption. The dimension is allowed to be much larger comparing with the sample size. An empirical study on a leukemia data along with synthetic data analysis are employed to validate the proposed tests.
