Exponential smoothing is widely used for forecasting economic and financial time series data. The Exponential Smoothing Statlet helps analysts quickly select an exponential smoothing model by letting them change the smoothing parameters dynamically. The effect on the forecast function and the error statistics is immediately visible as the parameters are changed. An Optimize button may also be used to find values of the smoothing parameters that minimize the one-ahead forecast errors.
