de student heeft een goede berekening gemaakt hier, de tijdreeks is stationair gemaakt door de kleine en de grote d gelijk aan 1 te zetten. en de lambda gelijk aan 0,5. we kunnen nu zien dat de meeste lijnen binnen het betrouwbaarheidsinterval liggen. het patroon is weggewerkt en ook de seizoenaliteit is gedifferentieerd.

deze vorige oplossing hoort bij een andere vraag. 
de stap 4 van de student is ook goed opgelost.  
de stappen die je moet overlopen voor het analyseren van een AR proces zijn de volgende: 
-	Is er een lange termijn trend?  
We kijken hiervoor enkel naar ongeveer de vijf eerste lijntjes bij de ACF. Deze vertonen gelijkenissen met de ACF van het AR proces. er is namelijk een dalend patroon te herkennen in de eerste 5 lijntjes en ze zijn alle 5 significant positief. 
Welke orde?  
Hiervoor kijken we naar PACF, je ziet dat er 2 streepjes significant zijn. maar het 3e ligt er heel dicht bij, dus voor zeker te zijn nemen we deze er ook bij  p moet dus gelijk zijn aan 3 
 
-	Is er een seizoenaal patroon?  
We kijken hiervoor naar lag 12,24,36,48.. Je ziet op het zicht geen patroon.  
P=0 
 
de conclusie is een AR(3) proces. dit heeft de student ook bekomen en heeft dus de opdracht tot een goed einde gebracht. 
 
dezelfde stappen doen we ook met het analyseren van een MA proces. 
-	eerst gaan we kijken of er ook een MA proces aanwezig is. Hiervoor kijken we opnieuw naar de PACF. Het gaat hier om de negatieve correlatiecoëfficiënten, onder 0. Wat mij opvalt zijn de significante negatieve pieken om de twaalf maanden. Dit wijst op seizoenaliteit. Die pieken convergeren naar 0. Dit is typisch voor een MA proces. In het algemeen is er niet echt een trend merkbaar aan de onderkant. q=0  
Er is wel een seizoenale trend. Hiervoor moeten we kijken naar de ACF. Het eerste seizoenale streepje, op lag 12, komt significant buiten het betrouwbaarheidsinterval. Het streepje bij lag 24 al niet meer. Q=1. Er is dus een SMA(1) proces aanwezig. 
 
de student heeft een goede berekening in conclusie gemaakt.
