4.3 Using the single randomless series 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20, compute a forecast for period 11 using: (i) the method of single exponential smoothing, (ii) Holt's method of linear exponential smoothing. Find the optimal parameters in both cases. (a) Which of the two methods is more appropriate? Why? (b) What value of a did you use in (i) above? How can you explain it in light of equation (4.4)? (c) What values of a and ß did you use in (ii) above? Why?
