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. References [ 1] WebbSimpleExpSmoothing.predict(params, start=None, end=None) In-sample and out-of-sample prediction. Parameters: params ndarray The fitted model parameters. start int, str, or …

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.

MS means start of the month so we are saying that it is monthly data that we observe at the start of each month. – ayhan Aug 30, 2024 at 23:23 Thanks for the reply.
