This article demonstrates that assumption of normal distributions does not have that consequence, although the multivariate normal distribution, including the bivariate normal distribution, does. To say that the pair ("X", "Y") of random variables has a bivariate normal distribution means that every constant (i.e. not random) linear combination "aX" + "bY" of "X"
