Webb3 feb. 2016 · At each time point, you extract the observations in the rolling window and use them to compute the statistic. You then move on to the next time point and repeat the computation. You might need to perform special computations at the beginning of the time series. The following SAS/IML program implements a simple moving average.
WebbTaking the simple average of all past data is the simplest way to smooth data. However, it is only a useful estimate for forecasting if there are no trends in the data. Any such trend is eliminated by taking the average.
