WebbFor this reason, simple exponential smoothing often performs better out-of-sample than might otherwise be expected, despite its "naive" horizontal trend extrapolation. Damped trend modifications of the linear exponential smoothing model are also often used in practice to introduce a note of conservatism into its trend projections. Webb21 sep. 2024 · Simple Exponential Smoothing (SES) SES is a good choice for forecasting data with no clear trend or seasonal pattern. Forecasts are calculated using weighted averages, which means the largest weights are associated with most recent observations, while the smallest weights are associated with the oldest observations: north america in koreanWebb5 feb. 2024 · This code fits a simple exponential smoothing (SES) model to the time series data in train. The SimpleExpSmoothing class from the statsmodels library is used to fit the model. The fit method is used to fit the model to the data, with a smoothing level of 0.5. The model is then used to make 48-step ahead forecasts for the time series data in test. north america information for kids
