student geeft correct antwoord.het idd zo dat we de LT trend en de seizoenaliteit er gaan uithalen door te diferentiëren. De periode is idd vrij groot en dit stelt de periode tussen de twee toppen voor, zoals de student correc aangeeft in zijn antwoord.

Het klopt dat er een lange termijn trend aanwezig is. Dit kan inderdaad bewezen worden aan de hand van de hoge spectrumwaarde uit de tabel. Er had nog vermeld mogen worden dat deze waarde een indicatie geeft van hoe sterk een golfbeweging aanwezig is.  Deze waarde vinden we door te kijken naar de frequentie met periode 144. Verder is het ook correct dat er een seizoenaliteit bestaat. Dit merken we aan de hoge spectrumwaarde bij een periode van 12 maanden. Tevens had nog vermeld kunnen worden dat de golfbewegingen met een kortere periode duidelijk minder belangrijk zijn dan deze met periode van 144 maanden. Dit kunnen we afleiden van de spectrumwaarden. Uit het raw periodogram blijkt dat er inderdaad seizoenaliteit aanwezig is door de dalende trend in de pieken. Verder is de conclusie in verband met het cumulative periodogram geheel correct. Aan de hand van het steil begin kunnen we inderdaad concluderen dat er een lange termijn trend aanwezig is. Ook het trapsgewijs verloop duidt op seizoenaliteit. Differentiëren is hier inderdaad nodig om deze trend en seizoenaliteit te verwijderen.
