Box's M test

Box's M test is a multivariate statistical test used to check the equality of multiple variance-covariance matrices. The test is commonly used to test the assumption of homogeneity of variances and covariances in MANOVA and linear discriminant analysis. It is named after George E. P. Box, who first discussed the test in 1949. The test uses a chi-squared approximation. Box's M test is susceptible to errors if the data does not meet model assumptions or if the sample size is too large or small. Box's M test is especially prone to error if the data does not meet the assumption of multivariate normality. (Wikipedia).
