      • Time series forecasting methods are based on the premise that you can predict future performance of a measure simply by analyzing its past results. These methods identify a pattern in the historical data and use that pattern to extrapolate future values. Past results can, in fact, be a very reliable predictor for a short period into the future.
      • Sometimes one of these simple methods will be the best forecasting method available; but in many cases, these methods will serve as benchmarks rather than the method of choice. That is, any forecasting methods we develop will be compared to these simple methods to ensure that the new method is better than these simple alternatives.

      • A good forecasting method will yield residuals that are uncorrelated. If there are correlations between residual values, then there is information left in the residuals which should be used in computing forecasts. This can be accomplished by computing the expected value of a residual as a function of the known past residuals, and adjusting the ...
      • MEAN (SIMPLE AVERAGE) METHOD Mean (simple average) method: The forecast for next period (period t+1) will be equal to the average of all past historical demands. In this illustration we assume that a simple average method is being used. We will also assume that, in the absence of data at startup, we made a guess for the year 1 forecast (300).

      • METHOD-I: SIMPLE MOVING AVERAGE (SMA) Introduction: A simple moving average (SMA) is the simplest type of technique of forecasting. Basically, a simple moving average is calculated by adding up the last 'n' period's values and then dividing that number by 'n'. So the moving average value is considering as the forecast for next period.

      • If someone was interested in making a forecast for Periods 14, 15, and 16, as well as Period 13, the best that could be done with the moving average method would be to make the "out period" forecasts the same as the most current forecast. This is true because moving average methods cannot grow or respond to trend.

      • The basic reason for the above classification is that different forecasting methods apply in each situation, e.g. a forecasting method that is appropriate for forecasting sales next month (a short-term forecast) would probably be an inappropriate method for forecasting sales in five years time (a long-term forecast).
    • Notice that each value of \(y_t\) can be thought of as a weighted moving average of the past few forecast errors. However, moving average models should not be confused with the moving average smoothing we discussed in Chapter 6. A moving average model is used for forecasting future values, while moving average smoothing is used for estimating ...
      • For a given average age (i.e., amount of lag), the simple exponential smoothing (SES) forecast is somewhat superior to the simple moving average (SMA) forecast because it places relatively more weight on the most recent observation--i.e., it is slightly more "responsive" to changes occuring in the recent past.
