Exponential smoothing

Exponential smoothing calculates the forecast based on the previous demand and the previous forecast. Offset periods is set to 1. You can use different Offset periods depending on purpose. The smoothing constant, alpha (α), is a value from 0 to 1. The higher the α, the faster the method reacts to changes in demand. This model is suitable for non-seasonal data that is fairly level and does not trend.
