The principles of first-order exponential smoothing are:
ReplyDelete. The older the time series values, the less important they are for the calculation of the forecast. More significance is then given to the closer time series values. By taking a smaller percentage of the older time series value and a higher percentage of the newer time series values; the exponential smoothing hopefully presents a good choice of future forecast values.
. The present forecast error is taken into account in subsequent forecasts.
