IBP standard dev

Hi all

Regarding the IBP 1705 info, there is new forecast model StdDevDelivQty to calculate standard deviation. For that there is a new key figure STDDEVDELIVQTY.

But inside the model it is calculating the RMSE error and saving in STDDEVDELIVQTY key figure. If I am not wrong RMSE is diferent than standard deviation STD.

Is that model ok for STD?

And when I try to add key figure to store forecast error in the model I don´t have any compatible key figure.

What should have the key figure to be compatible to store forecast error?

Thanks in advance

    Hello Carlos,

    Root Mean Square Error (RMSE) or Root Mean Square Deviation (RMSD) is also known as sample standard deviation - see Wikipedia Root-mean-square deviation.
    I also talked to the Development team and Key Figure STDDEVDELIVQTY is indeed used to store values of RMSE.

    Best regards,
