python - Holt-Winters time series forecasting with statsmodels
WebbThis is a full implementation of the holt winters exponential smoothing as per [1]. This includes all the unstable methods as well as the stable methods. The implementation of the library covers the functionality of the R library as much as possible whilst still being Pythonic. See the notebook Exponential Smoothing for an overview.
