Use the dataset ORG_QEarnings and perform the following regression: QE QEt-4 = a + ß* (QEt-1 - QEt-5) + Et where QE denotes quarterly earnings of Origin Energy Ltd in quarter t. a is the constant term (i.e., the intercept) and & is the error term. The regression should be performed using 20 quarters of earnings data. Report your regression estimates in the table below: α = Question 3 a. Based on your regression estimates, compute the expected quarterly earnings for the quarter ending March 31, 2019. b. Compute the forecast errors by applying the following model: QE+ - E(QE₂) |QE| FEt B = = where FE is the forecast error regarding the quarterly earnings of Origin Energy Ltd for quarter t (i.e., the quarter ending March 31, 2019). E(QE) denotes the expected quarterly earnings of Origin Energy Ltd for the quarter ending March 31, 2019. c. Looking at the value of FEt, what is your expectation regarding the direction of the short-term movement in the stock price of the company?
