Abstract
Additive seasonal models and multiplicative seasonal models can be forecast using general exponential smoothing and Winters' methods. The two forecasting methods were compared using 47 of the 1001 time series which were used in the M-competition. Values of the optimal smoothing constants found when fitting the models are shown. Although Winters' models always resulted in a better squared error fit, these models gave a better forecast in only 55% of the series.

A critical review of exponential smoothing since the original work by Brown and Holt in the 1950s is shared, which concludes that the parameter ranges and starting values typically used in practice are arbitrary and may detract from accuracy.

Seasonal series can be forecast by using Brown's adaptive forecasting method because explicit expressions for the variance of the forecast error are derived without the use of numerical matrix inversion, making the computation of the forecasts simple.
