Hello,
I am applying a zscore transformation to the X and Y before I conduct partial least squares regression, which I believe both centers (subtracts the column mean from each observation in the column) and scales (divides the centered values by the column standard deviation). How can I convert the RMSE values obtained from ztransformed values back to the scale of the original, untransformed variables?
Thank you!
