Question

A moving average system is used for forecasting weekly demand.

F 1 (t) and F 2 (t) are sequences of forecasts with parameters m 1 and m 2,

respectively, where m 1 and m 2 (m 1 > m 2) denote the numbers of

weeks over which the moving averages are taken. The actual

demand shows a step increase from d 1 to d 2 at a certain time.

Subsequently,
