PA: Issues with DATE
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...

Hello Christoph,This model is expecting one single row per quarter. So you need to aggregate the records beforehand. You need something like this Quarter,Quantity2007-Q1, 102007-Q2, 122007-Q3,...

Is it possible to create a new column in PA based on two existing columns?

Hi Christoph, yes that's possible via the manipulation tools pane or the function builder - depending on what exactly you'd like to do. There are also tutorials available which you'll find on the...

Well, if I create a new clomun like mentioned by Andreas, PA is still using the same time hierarchy as before. So how can I tell the algorithm which time hierarchie he should use? Actually as a user I...

Hi Christoph, it sounds like you didn't aggregate the data by quarter?When using "R-Triple Exponential Smoothing" the input data must be aggregated by the period type you want to predict. So data that...

Hi Andreas, thank you, its working with the algorithm you´ve mentioned. Still its not working with the R algorithm.What do you mean by aggregate? That I have to create a new column containing YEAR and...

Re: PA: Issues with DATE
Glad it's working now with the internal algorithm :-) For using the R algorithm the data needs to be summarised by quarter. That's what I meant with aggregations. So all values from Januar, February,...
