How to do a Sales Forecast with Exponential Smoothing

Webb24 juli 2024 · When there is no detectable trend or seasonality associated with your demand history, or something has disrupted the trend and/or seasonality, simple time series methods (i.e. naïve and simple exponential smoothing) will often generate a flat-line forecast reflecting the current demand level. 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.
