- External validation samples were predicted using the following calibration models: the PLS-1 GX.Release and GX.Yield calibration models, the PLS-2 G.Release and X.Release calibration model, and the PLS-2 G.Yield and X.Yield calibration model. “Factors:” the optimal number of factors for the model. The RMSEP values are higher than the uncertainty of the primary analytical methods.
-
RMSEP root-mean-square-error of the prediction of the validation samples, R
2 square of the correlation coefficient of the predicted samples.
