Question: Refer to the gasoline sales time series data in Table 15.1.
- Compute the four-week and five-week moving average for the time series.
- Compute the MSE for the four-week and five-week moving average forecasts.
- What appears to be the best number of weeks of past data (three, four or five) to use in the moving average computation? Recall that MSE for three-week moving average is 10.22.
