Situatie 1: lambda=1 / d=0 / D=0

De grafiek vertoont duidelijk een lange termijn trend.  d op 1 zetten
De grafiek vertoont niet duidelijk seizoenaliteit.  D blijven we af

Situatie 2: lambda=1 / d=1 / D=0

De grafiek vertoont duidelijk seizoenaliteit. Wederkerend (langzaam dalend) patroon bij lag 12, 24, 36,...

We moeten dus ook seizoenaal differentiëren.  D=1

Situatie 3: lambda=1 / d=1 / D=1 (heb je gedaan in volgende berekening)

• Vervolgens nemen we onder de module ‘Time series Analyses (new)’ de (Partial) Autocorrelation Function waarbij we de time lags op 60 instellen aangezien onze tijdreeks lang genoeg is, d en D laten we op nul en ook de seasonal period laten we op 12 staan.

http://www.freestatistics.org/blog/index.php?v=date/2008/Dec/07/t12286539706aloo6eiuv47chf.htm

We merken een lange termijntrend op, en zien een langzaam dalende autocorrelatie.

• Spectrale analyse via de module ‘Time series Analyses (new): we laten alles staan behalve de seasonal period die we op 12 zetten. http://www.freestatistics.org/blog/index.php?v=date/2008/Dec/07/t1228655690jdfz8t3tzklgr55.htm

Er is sprake van een lange termijntrend daar het spectrum enkel in het begin heel groot is.

Op het cumulative periodogram zien we dat de plot spectaculair stijgt. Vanuit deze analyse kunnen we afleiden dat er een dalende lange termijn trend is. Dit kunnen we besluiten doordat we zien dat de lage frequentie golven dominant zijn. 70% van de grafiek wordt bepaald door deze lange termijn trend. We zien ook seizonale pieken. We kunnen hierbij opnieuw besluiten dat we d en D instellen op 1.

Hier had ik meer time lags moeten nemen om een duidelijkere grafiek te krijgen. http://www.freestatistics.org/blog/date/2008/Dec/15/t1229339092dwcf8qx8uqx5nnq.htm, Als we dit doen zien we hier een duidelijke lange termijn trend die langzaam daalt. Er is ook enige vorm van seizoenaliteit te zien, om de 12lags bereikte de autocorrelatie een relatief hoogtepunt om vervolgens weer aftezwakken. De waarden in de tabel bevestigen dit tevens. Het onderzoek naar seizoenaliteit vereist echter meer onderzoek.
