Simpleexpsmoothing documentation
Webb21 apr. 2024 · SARIMA (Seasonal ARIMA) is a classical, statistical forecasting method that predicts the forecast values based on past values, i.e lagged values (AR) and lagged errors (MA). Unlike Holt-Winter's (or ETS), it needs the time series to be stationary before it can be used. That's where the "Integrated" part comes from.

Webb12 feb. 2024 · Thanks very much for this report! I think this can be pretty easily fixed by using _initialization_heuristic if we have at least 10 observations and use _initialization_simple if we have fewer than that.. I could not see a good workaround for this at the moment, other than the fact that if you are focused on linear (not muliplicative) … WebbFor any \(\alpha\) between 0 and 1, the weights attached to the observations decrease exponentially as we go back in time, hence the name “exponential smoothing”. If \(\alpha\) is small (i.e., close to 0), more weight is given to observations from the more distant past. If \(\alpha\) is large (i.e., close to 1), more weight is given to the more recent observations.
