Together, the formula gives us the ratio of the chances of both events occurring … WebIt is worth pointing out that the proof below only assumes that Σ22 is nonsingular, Σ11 and Σ may well be singular. Let x1 be the first partition and x2 the second. Now define z = x1 + Ax2 where A = − Σ12Σ − 122. Now we can write. cov(z, x2) = cov(x1, x2) + cov(Ax2, x2) = Σ12 + Avar(x2) = Σ12 − Σ12Σ − 122 Σ22 = 0.
