The Exponential Smoothing Forecast tool uses the Holt-Winters exponential smoothing method to decompose the time series at each location of a space-time cube into seasonal and trend components to effectively forecast future time steps at each location. The primary output is a map of the fi...
In this setting, selecting and using a forecasting method may appear to be somewhat ad hoc. The selection of the method is generally based on recognising key components of the time series (trend and seasonal) and the way in which these enter the smoothing method (e.g., in an additive, ...
If the data which is obtained has no trend and no seasonal pattern, then the single exponential smoothing method for forecasting the time series is primarily used. This method makes use of weighted moving averages with exponentially decreasing weights. The single exponential smoothing method formula ...
This paper introduces three approaches to forecasting interval-valued time series. The first two approaches are based on multilayer perceptron (MLP) neural networks and Holt’s exponential smoothing methods, respectively. In Holt’s method for interval-valued time series, the smoothing parameters are ...

The Exponential Smoothing method of forecasting is a commonly used method to make forecasts based on a times series data set. Other common methods are thenaive forecast method, theweighted moving averages,the moving averages forecast method, and the linear trend forecasting method, just to mention...
Introduction to Holt-Winters Exponential Smoothing The Holt-Winters method is an advanced method to forecast values. It considers seasonality, and trend effects while predicting the forecast. The formula is: Ft+k = (Lt+k*Tt)*St-m+k Where, F = Forecasted Value L = Level T = Trend M = ...
