Many multivariate statistical methods call upon the assumption of multivariate normality. However, many researchers fail to test this assumption. This omission could be due either to ignorance of the existence of tests of multivariate normality or confusion about which test to use. Although at least 50 tests of multivariate normality exist, relatively little is known about the power of these pr...

The main critique is that the theoretical connections between the concepts of reference values, normality, and health are weak. In this paper, we analyze especially one attempt in veterinary medicine to establish such a theoretical connection. We find that this attempt fails because it is circular. In conclusion, we w...
