Question
Suppose that we use an Exponential smoothing forecast with the smoothing factor alpha=0.25 =0.25 to forecast the value of the time series during period 6.
Suppose that we use an Exponential smoothing forecast with the smoothing factor \alpha=0.25=0.25 to forecast the value of the time series during period 6.
What is the value of the MAPE (mean absolute percentage error) of this forecast rounded to the nearest percentage?
| Period | Value ($) |
| 1 | 34.65 |
| 2 | 34.32 |
| 3 | 31.59 |
| 4 | 38.59 |
| 5 | 34.87 |
