Webb27 sep. 2024 · For this, we import the SimpleExpSmoothing class from statsmodels.tsa.api. We pass our time series to the class and then use the fit() method to smooth the time series based on a given smoothing ... 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.
