Figure 1 – Time Series Testing data analysis dialog box The Schwert criterion calculates the lag based on the Excel formula =ROUND(12 * (n/ 100) ^ (1 / 4), 0) which in this case is ROUND(12*(22/100)^(1/4),0) = 8. The AIC criteria is then used with lags = 8. ...
A second way to model seasonality is to assume thatsi=μm(i)+εiwhereεiis a purely random time series andμ0, …,μc-1are constants wherem(i) = MOD(i,c). A third approach is to model seasonality as a sort of random walk, i.e.si=μm(i)+si-c+εi. Ifμ0= … =μc-1...
