Simple ExponentialSmoothing
Unlike decomposition, which uses the entire history of a product as the forecast input, simple exponentialsmoothing uses a weighted moving average. Because simple exponentialsmoothing seeks to reduce, or smooth out, the irregular patterns...

polynomial, where the goodness-of-fit increases with the order of the polynomial. Higher-order polynomials, however, quite frequently display insufficient smoothing properties. This problem can be avoided by relying on a piecewise polynomial whereby the higher-order polynomial is approximated by a sequence of...
based on Univariate Modelling Techniques i.e. Naïve with Trend Model, Average Change Model, Average Percent Change Model, Single ExponentialSmoothing, Double ExponentialSmoothing and ARESS method. These models are normally used to determine the short-term forecasts (one month ahead) by analyzing the pattern...
ExponentialSmoothing Models1 Professor Thomas B. Fomby Department of Economics Southern Methodist University Dallas, TX June 2008
Introduction The formulation of exponentialsmoothing forecasting methods arose in the 1950’s from the original work of Brown (1959, 1962) and Holt (1960) who were working...

FORECASTING TECHNIQUES
Moving Averages
When seasonal patterns exist without trends, simple smoothing methods work well with deseasonalized data. Intrinsic forecasting methods are those that use the past behavior of series to predict the future value of that same series. The term intrinsic denotes...
