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).
