1. (a) (5 points) Prepare an S matrix Sex2 where O and E are binded with their columns, and please specify its possible rank. (b) (5 points) Can you conclude that these columns are independent by looking the first two rows? (c) (5 points) Please calculate Var(E) (Not the statistical variance). (d) (5 points) Please estimate the covariance matrix of S, namely Cov(S) = ? (Not the statistical covariance) (e) (5 points) Calculate A Cov(s) = ? () (5 points) What about the rank of Cov(S), namely R(Cov(S)), equivalent to 1? () (10 points) Statistical variance of E can be calculated as of d(E)'d(E) where d is the N deviance vector of E. So, what is az?
