Cov sigma
WebFind Cov(X, Y) . Solution Now we discuss the properties of covariance. Lemma The covariance has the following properties: Cov(X, X) = Var(X); if X and Y are independent then Cov(X, Y) = 0; Cov(X, Y) = Cov(Y, X); Cov(aX, Y) = aCov(X, Y); Cov(X + c, Y) = Cov(X, Y); Cov(X + Y, Z) = Cov(X, Z) + Cov(Y, Z); more generally, WebNational Center for Biotechnology Information

Cov ( X) = E [ ( X − E ( X)) ( X − E ( X)) T]. Plug in X = A Z and use matrix algebra to simplify this to. Cov ( X) = A [ E ( Z − E ( Z)) ( Z − E ( Z)) T] A T = A [ Cov ( Z)] A T. By assumption, the Z 1, Z 2 are standard normals, so that the covariance matrix for Z is the identity matrix ...
