Je bent de lag's vergeten in te stellen deze kunne het best op 12 of 36 ingesteld worden.

Bij Task 3 heb je dezelfde fout gedaan als er in Task 1 Q2 zat, namelijk voor bepaalde assumpties naar de verkeerde grafieken gekeken.

assumptie 1 controleer je aan de hand van de lag plot en autocorrelation function (die enkel gemaakt worden bij het instellen van de lags)

assumptie 2 controleer je aan de hand van de density plot en de q-q plot

assumptie 3 en 4 controleer je aan de hand van de run sequence plot
