(Continuation of Exercise 3.5) Return to the wages series. (a) Consider the residuals from a least squares fit of a quadratic time trend. (b)Perform a runs test on the standardized residuals and interpret the results. (c) Calculate and interpret the sample autocorrelations for the standardized residuals. (d)Investigate the normality of the standardized residuals (error terms). Consider histograms and normal probability plots. Interpret the plots.
