De lags hadden ingesteld moeten worden.
http://www.freestatistics.org/blog/index.php?v=date/2008/Nov/03/t1225738073d4x22zj6nsnjxv3.htm => lags ingesteld

1.Bij de eerste assumptie moeten we naar de lag plot gaan kijken en dan zien we dat de punten toch redelijk dicht tegen de lijn liggen dus dit zou kunnen duiden op seizonaliteit.

2.Dit is correct geïnterpreteerd

3.Hiervoor moet gekeken worden naar de run sequence en dan zien we dat het eindigt met een daling, dit zou kunnen betekenen dat het niveau op lange termijn niet constant blijft.

4.Als we kijken naar de spreiding bij de run sequence dan zien we dat die niet overal even breed is.

Q7: net als bij task 1 gebruikte ik de foute plots om de assumpties te testen. Voor asumptie 3 zie je dat het gemiddelde tussen de betrouwbaarheidsintervallen zit en min of meer constant blijft.
http://www.freestatistics.org/blog/index.php?v=date/2008/Nov/03/t1225738939em1r01lgxza88fq.htm

Q8 is correct opgelost.
Bij Q9 gebruikte ik de juiste methode.
Bij Q10 is er inderdaag geen seizoensgebondenheid terug te vinden als we de run sequence plot bekijken. Ook op de lag plot is hier niks van te merken.

ASS 1: de lags moeten worden ingesteld op 36, anders kan je geen uitspraken doen over eventuele seizonaliteit. Als we dit doen zien we dat de punten dicht tegen de lijn komen te liggen wat duidt op seizonaliteit.
