Several one sample tests use the same test statistic Tn with different estimators of the variance V(Tn). Rather simple theory from U-statistics is used to find V(Tn), resulting in an estimator that is quick to compute when H0 is true. Some two sample tests for H0: mu1 = mu2 are also considered.46en-USHigh dimensional testsHotelling’s T^2 testSOME SIMPLE HIGH DIMENSIONAL ONE AND TWO SAMPLE TESTSThesis
