Weblecture 23: the mgf of the normal, and multivariate normals 4 Example: Multivariate normal The standard multivariate normal distribution gives a point x 2Rd, with pdf f(x) = ek xk2/2 (2p)d/2. To generalize this with arbitrary variance and mean, we need the concept of covariance matrix. If S is a positive definite matrix, the pdf of the ...
