WebDeﬁnition 3. A random vector X has a (multivariate) normal distribution if for every real vector a, the random variable aT X is normal. PROOF OF EQUIVALENCE In the course of the proof of Theorem 1 in the previous lecture, we argued that if X is multivariate normal, in the sense of Deﬁnition 2, then: http://www.stat.yale.edu/~pollard/Courses/241.fall97/Normal.pdf
