In het begin van de grafiek is er een vrij steile outlier die valt rond eind 2000. Misschien is hier toen iets gebeurd. In onderstaand document staat wat uitleg over de stijging, weliswaar in Nederland maar ik neem aan dat in België de oorzaak dezelfde was.

De uitschieter in het begin zal voor problemen zorgen. Je kan ofwel die waarde eruit halen, maar dit moet je dan wel melden in je documenten of een andere dataset zoeken.

Ik heb dezelfde commentaar. Probeer de outliner in het begin te verklaren en nadien op een correcte wijze weg te werken. Ik zou met gemiddeldes werken.

Ik kan me alleen maar aansluiten bij de voorgangers. De uitschieters kunnen mogelijk voor problemen zorgen indien hier geen gegronde uitleg voor is. Als je deze kan wegwerken kan dit nog steeds een nuttige tijdreeks zijn.

De uitschieter kan inderdaad voor problemen zorgen. Als je een logische verklaring vindt kan deze tijdreeks nog nuttig zijn.
