explain Q 16

14. Consider the following AR(2) model. What is the optimal 2-step-ahead forecast for y if all information available is up to and including time 1, if the values of y at time 1, 1-1 and 1-2 are - 0.3, 0.4 and -0.1, respectively, and the value of u at time 1-1 is 0.3? y = -0.1 +0.75y-0.125y + u (a) 0.1 (b) 0.27 (c) * -0.34 (d) 0.30. 15. What is the optimal three-step-ahead forecast from the AR(2) model given in Question 14? (a) -0.1 (b) 0.27 (c) -0.34 (d) -0.31. 16. Suppose you had to guess at the most likely value of a one hundred-step-ahead forecast for the AR(2) model given in Question 14 - what would your forecast be? (a) -0.1 (b) 0.7 (C) -0.27 (d) 0.75. 14.
