Refer to exercise 14.26. (a) Plot the dollar/pound exchange rate data. Copy and paste the chart so that you have four copies (one for each α). (b) Perform simple exponential smoothing (using Excel’s Data Analysis or other software such as Minitab) using α = .05, .10, .20, and .50. (c) Which value of α do you prefer? Why? (d) Is exponential smoothing appropriate for this kind of data?
14.26 (a) Make a line chart and fit an m-period moving average to the exchange rate data shown below with m = 2, 3, 4, and 5 periods. For each method, state the last MA value. (b) Which value of m do you prefer? Why? (c) Is a moving average appropriate for this kind of data?
