Double exponential smoothing. Double exponential smoothing is used when there is a trend in the time series. In that case, we use this technique, which is simply a recursive use of exponential smoothing twice. …
Exponential smoothing is a rule of thumb technique for smoothing time series data using the exponential window function. Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time. It is an easily learned … See more The use of the exponential window function is first attributed to Poisson as an extension of a numerical analysis technique from the 17th century, and later adopted by the signal processing community in the … See more • R: the HoltWinters function in the stats package and ets function in the forecast package (a more complete implementation, generally resulting in a better performance ). • Python: the holtwinters module of the statsmodels package allow for … See more 1. ^ "NIST/SEMATECH e-Handbook of Statistical Methods".
