WebbExponential smoothing weights past observations with exponentially decreasing weights to forecast future values: This smoothing scheme begins ... (\alpha\) so the value which … WebbThe value of $\alpha$ is called the smoothing constant. For whatever reason, $\alpha$ = 0.2 is a popular default choice of programs. This puts a weight of .2 on the most recent observation and a weight of 1 − .2 = .8 on the most recent forecast. With a relatively small value of $\alpha$, the smoothing will be relatively more extensive.
