Zie Q3: op deze manier kan je te weten komen hoeveel keer we d en D zouden moeten transformeren.

d=0 wil zeggen dat er geen lange termijn trend is
D=0 wil zeggen dat er geen seizoenaliteit is.

Als er wel 1 van de 2 vorige is, gaan we d en/of D op 1, 2 of 3 zetten (afhankelijk van welke orde de trend/seizoenaliteit is) om zo de trend of seizoenaliteit er uit te halen. Op die manier word de tijdreeks stationair gemaakt. Dit noemt men differentiëren.

Zie Q5: Zo kan je de lambda berekenen. Door deze in te vullen ga je de tijdreeks wederom transformeren en zo de reeks nog meer stationair maken.
