Suppose that (X1, Y1, Z1) = (7.0, 2.5, 1.9),(X2, Y2, Z2) = (6.3, 9.6, 4.1), (X3, Y3, Z3) = (6.9, 3.7, 12.4), (X4, Y4, Z4) = (3.6, 12.1, 6.5), (X5, Y5, Z5) = (9.0, 6.4, 11.2), (X6, Y6, Z6) = (3.0, 6.2, 7.7), and (X7, Y7, Z7) = (4.2, 0.4, 8.2) represent a random sample of size n =7 from a trivariate probability distribution. Estimate the partial correlation τXY /Z (8.47) between X and Y conditional on Z (See Comment 30).
