My friends and I shared the simple exponential smoothing method, simple exponential smoothing can only predict those at a constant level and no seasonal changes in the time series, today and you share the non-constant level of growth or reduce the trend, The time series prediction algorithm without seasonal additive model---Holt exponential smoothing (Holt).The H

We have a complete understanding of the time series sequence and decompose the time series, and today we share the simplest of the common predictive algorithms with the small partners: simple exponential smoothing. Simple exponential smoothing applies to the available additive model descriptions, and is at a constant level and has no seasonal variations in time series for short-term predictions.The simple e

Today goes on to the most complex time series in exponential smoothing: a predictive algorithm that has a time series of increasing or decreasing trends and having seasonal fluctuations is holt-winters and shared with everyone. This sequence can be decomposed into the horizontal trend part, the seasonal fluctuation part, therefore these two factors should have the corresponding parameter to control in the algorithm.The holt-winters algorithm provides
