When the underlying mean of a time series is very stable and there are no trend, cyclical, or seasonal influences:
◦ a simple moving-average forecast with n = 3 should outperform a simple moving-average forecast with n = 20.
◦ a simple moving-average forecast with n = 20 should outperform a simple moving-average forecast with n = 3.
◦ an exponential smoothing forecast with α = 0.30 should outperform a simple moving-average forecast with α = 0.01.
◦ a simple moving-average forecast with n = 20 should perform about the same as a simple moving-average forecast with n = 3.
