Hi guys,
I just tried to use the R-triple exponential smoothing algorithm to create a forecast. I´m using a dataset of 2007 and 2008 and I want to forecast quarter 1,2,3 and 4 of 2009. Unfortunately PA (SP10) has some issues taking the right year. Instead PA is counting the years like shown in the jpeg attached.
Any thoughts? Regards, Christoph.
