Bij randomness had ik me ook moeten baseren op de lag plots. Zo had ik bij de eerste lag plot kunnen vaststellen dat de puntenwolk niet rond de recht liggen wat er dus op wijst dat men geen uitspraak kan doen over het heden als men zich baseert op 1 maand geleden. Om de seizoensgebondenheid na te gaan had ik het aantal lags op 36 moeten zetten. In deze link vind je de juiste oplossing: http://www.freestatistics.org/blog/date/2008/Nov/02/t1225628731e3y2qdhb02609a2.htm
Aan de hand van deze grafiek kan ik concluderen dat een sterke positieve correlatie is.

De vaste verdeling is volledig juist weergegeven en geïnterpreteerd.

De analyse van de vaste component is volledig fout. Ik had me inderdaad moeten baseren op de runsequense plot. Als ik dan het gemiddelde op lange termijn had geanalyseerd, had ik vastgesteld dat het gemiddelde in die periode steeg. Er kan dus niet gesproken worden over een vaste component.

De analyse van vaste variatie is eveneens foutief. De schommelingen in het begin van de periode zijn in beperkte mate sterker dan de schommelingen in het tweede gedeelte van de periode.
