Bij elke herberekening die je maakt, zullen de 2 laatste grafieken niet weergegeven worden omdat je vergeet de 'lags' in te vullen. Zet deze op 12 of 36 en je zal de laatste grafieken wél te zien krijgen. Een lag = 12 geeft je eveneens de mogelijkheid om overzichtelijk te zoeken naar seizonaliteiten.

nr1: Als we in de blog het aantal lags aanpassen naar 36 merken we dat er duidelijk wel autocorrelatie is. De autocorrelatie is hier niet seizoensgebonden

Nr 2: Het histogram vertoont een redelijk mooie driehoekvorm en de density plot is mooi bell shaped. Er zit een zeer kleine knik in maar dit is geen rede om aan te nemen dat deze reeks geen normaal verdeling heeft. Hier is dus geen ongelijke verdeling.

nr 3: De student zegt er niet bij naar welke grafiek hij heeft gekeken. Daardoor vind ik dit een zeer verwarrende uitleg. Hier moet je de run sequence plot gebruiken. Als je wilt kijken of het gemiddelde constant is moet je de central tendancy toepassen. Het gemiddelde schommelt hier een beetje maar blijft toch constant.

nr4: Hier hebben we een constante daling. Hier is de schommeling niet zo erg en er zittengeen ourliers in dus je hebt hier een vaste spreiding.
