Gaussian Random Vectors - University of Utah
www.math.utah.eduGaussian Random Vectors 1. The multivariate normal distribution Let X:= (X1 X) be a random vector. We say that X is a Gaussian random vector if we can write X = µ +AZ where µ ∈ R, A is an × matrix and Z:= (Z1 Z) is a -vector of i.i.d. standard normal random variables. Proposition 1.
