Referring to other attributes and data rows when generating new attributes
Emandal
Hi guys, I am a newbie in RapidMiner and am trying to do Time Series Analysis combined with sensex. I have forecasted values with Arima model and I would like to compare forecasted value in row x with real value in row x-1. I tried using Generate attributes operator but I am unsure on how to reffer to different attributes and rows. Does anyone have a suggestion on how to solve this?
Thanks

Hi
@Emandal
,
I think you need of the
Lag
operator and after that you can use the
Generate Attributes
operator to perform the comparison between the row x and row (x-1).
