Jouw antwoord is juist maar onvolledig. Voor we naar de optimale lambda waarde kijken zien we eerst best naar het standard mean plot om eventueel storende outliers te ontdekken. Hier toont Standard Deviation-Mean plot toont ons een positief lineair verband. Wat wel onrustwekkend is, is de outlier die zich bovenaan bevindt. In dit geval stoort dit niet omdat deze niet volledig links of rechts ligt. Moest dit wel het geval zijn is het best om dit eerst te corrigeren omdat deze een grote storing kan veroorzaken op de helling van de curve.  
In de tabel zien we dat er minder dan 1% kans is dat we ons vergissen bij het verwerpen van de nul hypothese. Maar ook de helling is significant en dus niet aan het toeval te wijten. De optimale lambda voor de transformatie is 0,47. Een waarde van 0,5 zal gemakkelijker zijn voor de verdere uitwerking van de modelvergelijking en dus passen we deze optimale waarde lichtjes aan. Dit kan in dit geval omdat de SD 0,11 is en de lambada dus lichtjes kan schommelen rond de gegeven optimale waarde.

Goed, kleine aanvulling:als de p-waarde kleiner is dan 0,5 dan is er een significant verschil van nul. We mogen dan ook verder gaan kijken naar de tweede tabel. Hier kunnen we de waarde van lambda aflezen, deze bedraagt 0.467057973925014. Om de waarde van lambda af te ronden kunnen we dit doen binnen het betrouwbaarheidsinterval.Dit is - 2x de SD als ondergrens en 2x keer de SD als bovengrens.De output is wel maar kort besproken.

Ook nog: 
De beta is hier positief, dit betekent dat er een positief verband is tussen de spreiding en het niveau. 
Om na te gaan of beta van het toeval afhangt, zijn er twee voorwaarden waaraan voldaan moet worden: 1. er moet een consistent verband zijn tussen het gemiddelde en de spreiding 2. de p-waarde moet kleiner of gelijk zijn aan 5%. 
Aan deze twee voorwaarden moet voldaan worden. De computer zal altijd de waarde van lambda berekenen ook al is dit zinloos.

Je hebt inderdaad de Lamba berekend. Wel had je dit beter mogen uitleggen. De P waarde in de eerste kolom is kleiner dan 5%, waardoor je de nul hupothes kunt verwerpen. Je hebt dan een lambda waarde van 0,46 gevonden. En je mag deze inderdaar afronden naar 0,5 omdat deze waarde zich binnen het betrouwbaarheidsinterval van 95% bevind.
2008-12-16 18:38:41 [Gert-Jan Geudens] [reply] 
Goede conclusie. De lambda is hier nuttig aangezien we een kleine p-waarde hebben gevonden. Als we in de standard-deviation mean plot een punt zouden toevoegen (bv. linksboven) zal dit niet zo een grote invloed hebben de regressielijn.

CORRECTIE VAN AL ONZE FEEDBACKS OP STEP 1 VAN DE UNEMPLOYMENT DATA :  
 
Als we linksboven in de standard-deviation mean plot een punt zouden toevoegen, zou dit de regressielijn wel vertekenen !
2008-12-17 08:13:50 [Jolien Van Landeghem] [reply] 
Je uitleg is wat mager. We zien in de bovenste tabel dat beta positief is. Er is dus een verschil tussen de spreiding en de standaardfout. Om na te gaan of dit verschil significant is, bekijken we de p value. Deze bedraagt 0.015 en is dus kleiner dan 0.05. Er is dus sprake van heteroscedasticiteit. Als we deze wegwerken en we vinden de waarden om seizoenaal en niet seizoenaal te differentiëren, dan bekomen we een stationaire tijdreeks. We gaan de data tot de -1.5e macht verheffenen om de heteroskedastischiteit weg te werken. Op de scatterplot kunnen we ook nagaan of er een consistent verband aanwezig is.  Dit kan je bevestigen, want je kan een rechte tekenen door de puntenwolk (hou er wel rekening mee dat we te maken hebben met een outlier, rechtsboven
