R²_C: coefficient of determination for calibration; R²_P: coefficient of determination for prediction; RMSEC: root mean square error of calibration; RMSEP: root mean square error of prediction; RPD: ratio of performance deviation; MSC: multiple scatter correction; MC: mean centering; and 1D and 2D: first and second derivative.
