11.7. Prove the statement before Eq. (11.9) that complete-data ML estimates of S are obtained from C

Question:

11.7. Prove the statement before Eq. (11.9) that complete-data ML estimates of S are obtained from C by simple averaging. (Hint: Consider the covariance matrix of the four variables U1 ¼ Y1 þ Y2 þ Y3 þ Y4; U2 ¼ Y1 Y2 þ Y3 Y4; U3 ¼ Y1 Y3, and U4 ¼ Y2 Y4.)
