De student heeft de nonsenscorrelatie uit vraag 7 omgevormd door middel van differentiatie tot een goede stationaire reeks.

Goede oplossing, dit is een stationaire tijdreeks.
2008-12-07 11:59:38 [Lana Van Wesemael] [reply] 
Aangezien je in de vorige vraag de lambda waarde vergeten bent zou het kunnen dat de grafiek er met de juiste lambda er anders uitziet. De lambda moet je invullen in het Box-Cox transformation parameter vakje.

Door een andere lambda waarde zou de tijdreeks er anders kunnen uitzien.
