Box's M test
Box's M test is a multivariate statistical test used to check the equality of multiple variance-covariance matrices.[1] 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.
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.[2] Box's M test is especially prone to error if the data does not meet the assumption of multivariate normality.[3]
