the moments of the **Gaussian** distribution. In particular, we have the important result: µ = E(x) (13.2) T. (13.3) We will not bother to derive this standard result, but will provide a hint: diagonalize and appeal to the univariate case. Although the moment parameterization of the **Gaussian** will play a principal role in our

assume E(X) = 0 in which case the **multivariate****Gaussian** (1) becomes f X(x 1,x 2,...,x p) = 1 (2π)p/2 det(Σ)1/2 exp − 1 2 xtΣ−1x (2) Now the matrix XXt is a p × p matrix with elements X iX j. (Note XtX is 1×1 but XXt is p×p.). One can show (by evaluating integrals) that (recall we are setting µ = 0) E(XXt) = Σ, that is, E(X iX j ...
