Het was hier niet de bedoeling om de ene tijdreeks door de andere te delen, de opdracht was nl. 'Your Time Series = constant + random component' Het is dus beter om hier bv. enkel de tijdreeks (Ontwikkeling van de prijzen in België ) te nemen en hierop verder te werken, om daarna de voorwaarden van dit model na te gaan, zal het ook nodig zijn hier de R code licht aan te passen door x<-x-gevonden gemiddelde in te voegen!

Ook hier was het model 'Ontwikkeling van de prijzen in België / Financiële situatie van de gezinnen = constant + random component' toegepast wat niet de bedoeling was. Het invoegen van x<-x-gevonden gemiddelde in de R-code van een enkel willekeurig gekozen tijdreeks was voldoende geweest om de oefening te kunnen oplossen.

Het was inderdaad niet de bedoeling om de twee tijdreeksen door elkaar te delen. Het had voldoende geweest om 1 tijdreeks te nemen.
