Some Extra Definitions Recall that, for a nonrandom real number c, and a random variable X, we have Var (cX) = e Var (X). In this problem we'll generalize this property to linear combinations! Let be a vector of real nonrandom numbers, and let be a vector of random variables (sometimes called a random vector). Last, define the covariance matrix to be the matrix with all the covariances ar- ranged into a matrix. When we talk about taking the taking...
