NettetUsing a simple moving average model, we forecast the next value (s) in a time series based on the average of a fixed finite number m of the previous values. Thus, for all i > m Example 1: Calculate the forecasted values of the time series shown in range B4:B18 of Figure 1 using a simple moving average with m = 3. Nettet3.3.3 Simple Moving Average. Naïve and Global Mean can be considered as opposite points in the spectrum of possible level time series (although there are series beyond Naïve, see for example ARIMA(0,1,1) with \(\theta_1>0\), discussed in Chapter 8).The series between them exhibit slow changes in level and can be modelled using different …

The notation “ 2×4 2 × 4 -MA” in the last column means a 4-MA followed by a 2-MA. The values in the last column are obtained by taking a moving average of order 2 of the values in the previous column.
