WebEach single variable has a univariate normal distribution. Thus we can look at univariate tests of normality for each variable when assessing multivariate normality. Any subset of the variables also has a multivariate normal distribution. Any linear combination of the variables has a univariate normal distribution. The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a specified mean and variance. Geary has shown, assuming that the mean and variance are finite, that the normal distribution is the only distribution where the mean and variance calculated from a set of independent draws are independent of each other.
