Brown’s Triple Exponential Smoothing

Brown’s Triple Exponential Smoothing is similar to Double Exponential Smoothing and Single Exponential Smoothing. However, the smoothing constant in Triple Exponential Smoothing is derived by “re-smoothing” the double smoothed constant from Double Exponential Smoothing. Since forecasts can be expressed as a function of the single, double and triple smoothed constants, this forecast procedure is known as Triple Exponential Smoothing. Brown’s Triple Exponential Smoothing is meant to be implemented on data showing a quadratic trend over time. The smoothing constant in this model should be chosen between .02 and .11. Triple Exponential Smoothing can forecast multiple time periods into the future.
