Zero Covariance Does Not Necessarily Imply Independence. Let X = −2, −1, 0, 1, 2 with Pr[X = x] = 1/5. Assume a perfect quadratic relationship between Y and X , namely Y = X 2. Show that cov(X, Y ) = E(X 3) = 0. Deduce that ρXY = correlation (X, Y ) = 0. The simple correlat...

You will have found in Exercise 7.7 that the estimates of the coefficients of PWEBEF and TENURE are different. This raises the issue of whether the difference is due to random factors or whether the coefficients are significantly different. Set up the null hypothesis H0: δ1 = δ...
