Accuracy of prediction for developed NIRS calibrations of protein content and soluble pentosan content

Model	Calibration				Validation
	N C	R C	$R_C^2$	SE	N V	Bias	R V	$R_V^2$	SE	SD
PC (%)	330	0.99	0.98	0.23	108	0.01	0.99	0.98	0.31	2.07
SPC (%)	321	0.91	0.82	0.18	107	–0.02	0.86	0.74	0.22	0.43

N _C and N _V denote sample sizes for calibration and validation, respectively; R _C and R _V refer to the correlation coefficients of calibration and validation, respectively; $R_C^2$ and $R_V^2$. represent coefficient of determination of calibration and validation, respectively; SE is standard error of calibration and validation, respectively; SD denotes the standard deviation within the validation set; PC, protein content; SPC, soluble pentosan content.
