Shapiro and Wilk's [Shapiro, S.S., Wilk, M.B., 1965. An analysis of variance test for normality (complete samples). Biometrika 52, 591-611] W-statistic was found to have competitive power performance in testing univariate normality. Generalizations of the W-statistic to the multivariate case...

Three quantile-quantile (Q-Q) plots are derived from a characterization for the multivariate normal distribution. The Q-Q plots can be easily used for detecting a possible departure from multinormality in high-dimensional data analysis. An example is illustrated to employ the plots in practice.

Based on Läuter's [Läuter, J., 1996. Exact t and F tests for analyzing studies with multiple endpoints. Biometrics 52, 964-970] exact t test for biometrical studies related to the multivariate normal mean, we develop a generalized F-test for the multivariate normal mean and extend it to...
