Bij deze vraag gaan we de central tendency met random component gebruiken. Bij de R-code gaan we dus 'x<-x-gemiddelde' invoegen.

We zien dat men zeer dicht bij 0 komt te liggen. Is niet helemaal 0, maar dat speelt niet zo'n rol. De lijn ligt tussen de twee stippellijnen van de betrouwbaarheidsintervallen. Het gemiddelde is dus 0 en is een robuust resultaat wat zelfs als we outliers wegnemen blijft gemiddelde 0.

Je gebruikt hier idd een techniek die nog niet gekend is en waarover ik dus ook nog geen uitspraak zal doen. Wel is het nuttig om bovenstaande uitleg te volgen. Je hoeft wel niet je R code aan te passen. Je kan ook het gemiddelde van al je datagegevens aftrekken in excel en vervolgens een nieuwe tijdreeks creëren.
