Webb8 feb. 2024 · The technique which works on this principle is called Simple exponential smoothing. Forecasts are calculated using weighted averages where the weights decrease exponentially as observations come from further in the past, the smallest weights are associated with the oldest observations: where 0≤ α ≤1 is the smoothing parameter.

Webb* simple exponential smoothing, however, a "smoothing parameter" - or * "smoothing constant" - is used to determine the weights assigned to the * observations. * * Exponential smoothing is a rule of thumb technique for smoothing time series data using the exponential window function. Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time. It is an easily learned and easily applied procedure for making some determination based on prior assumptions by the user, such as seasonality.

WebbHere we run three variants of simple exponential smoothing: 1. In fit1 we do not use the auto optimization but instead choose to explicitly provide the model with the α = 0.2 parameter 2. In fit2 as above we choose an α = 0.6 3. In fit3 we allow statsmodels to automatically find an optimized α value for us. This is the recommended approach.
