De lambda waarde lees je af van de SD-Mean Plot, niet van de VRM-matrix:

De p-waarde is klein en de B-waarde is significant verschillend van nul, dus we mogend de lambda-waarde aflezen; die is 0,34 of 0,4.

We zetten de seizonale periode op 12. Anders is het niet correct.We gaan nu ook eens de autocorrelation function toepassen. We zien inderdaad dat
