so you can get a better understanding of the outcome that will be provided by this solver. The idea behind Exponential Smoothing for making forecasts consists of estimating the data value of certain period based on the previous data value as well as the previous forecast, so that to attempt to correct for the deviation between the previous actual value and the prediction. The following formula is used to estimate the data value during period \(n\)

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 the naive forecast method , the weighted moving averages , the moving averages forecast method , and the linear trend forecasting method, just to mention a few.

Notice that this a calculator assumes no trend component. Use this calculator in case you want to compute exponential smoothing with trend component , for a more accurate prediction.
