Single exponential smoothing with a smoothing constant value of .25 puts the same weight on the most recent actual demand as a 4-period moving average.

Question

Quizplus · Accepted Answer

Single exponential smoothing with a smoothing constant of 0.25 puts 25% of the weight on the most recent actual demand and 75% on the previous forecast. In comparison, a 4-period moving average also puts 25% weight on the most recent actual demand (as it averages the last 4 periods equally). Therefore, both techniques put the same weight on the most recent actual demand.
