Forecasts, as the saying goes (applied to models in general) are always wrong but often useful. Exponential Smoothing is a self-correcting method of forecasting. This is normally considered a smoothing algorithm and has poor forecasting results in most cases. Posted on December 31, 2012 by mholt http://cran.r-project.org/web/packages/forecast/forecast.pdf. To accomplish this, I'll use a forecasting technique known as Exponential Smoothing. Time Series Forecasting – Exponential Smoothing. A good choice is to use simple exponential smoothing or a moving average as the naïve. This entry was posted in Uncategorized by mholt. I'd like to take an initial look at an innovative forecasting methodology using exponential smoothing models. In this workshop, we will explore methods and models for statistical forecasting. Forecasting using seasonal adjustment factors I went back today and compared the performance of my (more elementary) ETIStats model to the exponential smoothing model described by John for the year of 2011:. Off-the-shelf products like Forecast Pro or Autobox. This article will show in step-by-step instructions how to perform a demand forecasting technique called Exponential Smoothing in Excel. Forecasts will change with new each observation, but depending on the alpha factor of your exponential smoothing (e.g. For univariate forecasting, you can use Exponential smoothing models, intervention models, Box-Jenkins models, distributed lag models, vector autoregression models etc. The article familiarizes the reader with exponential smoothing models used for short-term forecasting of time series. X't = αXt + (1-α)X't-1 it is a weighted moving average with weights that decrease exponentially going backwards in time. There are three main versions of this technique, and I'll be using a version known as double exponential smoothing.
