Fig. 2.
Mean of the difference in amino acids predicted by protein linear regression or by NIRS calibration model compared to the measured value for the total dataset. Mean difference = Mean of [│Labn – P-Regn│/Labn × 100] or Mean of [│Labn – NIRSn│/Labn × 100], where Labn is the measured value, P-Regn is the value predicted by protein regression and NIRSn is the value predicted by the NIRS calibration.
