For the time series data presented in Table 9.10 calculate seasonal forecasts using the simple seasonal additive

Question:

For the time series data presented in Table 9.10 calculate seasonal forecasts using the simple seasonal additive exponential smoothing model.

Quarter 1 2 3 4 Table 9.10 1 17.15 19.87 20.53 20.78 2 16.80 15.87 17.13 18.11 3 13.85 19.67 20.29 20.94 Year

If we plot the time series as illustrated in Figure 9.44 we note that we have a definite pattern in the shape of the curve, which repeats over the same time period quarters.

This suggests a seasonal module would be appropriate.

Series value 30.00- 25.00- 20.00- 15.00- 10.00- 5.00- 0.00- 3 5 7 Time series plot Series 9 11 13 15 17 19 21
