Fout. De student moest de standard deviation mean plot berekenen. Dit is hier niet gedaan. Ik heb gereproduced wat er wel moest berekent worden: http://www.freestatistics.org/blog/index.php?v=date/2008/Dec/05/t1228484982zm3lsivm3zg8u6g.htm 
Dan moest er gezegd worden dat er toch een duidelijke lineaire trend te zien is.

Er is hier inderdaad een verkeerde berekening gebeurd.  
Ik heb deze computation gedaan: http://www.freestatistics.org/blog/index.php?v=date/2008/Dec/02/t1228247220lkjrlucgyv5n8vj.htm 
 
Als conclusie kan men hierop zeggen: 
 
Uit de standaard deviation-mean plot kunnen we concluderen dat er een trendmatig verloop is terug te vinden. Er is hier eveneens sprake van seizoenaliteit.  
De spreiding is links onder kleiner dan de spreiding die zich rechts boven bevind.  
Door een lambda toe te voegen kan men de tijdreeks transformeren waardoor de spreiding harder naar een diagonaal zal deinen. Een lambda van 1 geeft bijvoorbeeld een perfecte rechte. De bedoeling van deze transformatie is om de tijdreeks stationair proberen te krijgen. Hier voor moet je zien dat de spreiding gelijk loopt door de tijd en hierdoor wordt de trend eruit gehaald.
