Correlation analysis of PLS modeling using samples in calibration set. A correlation analysis of predicted (PLS model of FT-NIR) versus experimentally determined monosaccharide composition (mol%) of rice leaf samples. Data represents the iterative process of K-fold cross validation of the 206 leaf samples analyzed by both FT-NIR and HPAEC. The correlation coefficient between predicted and experimental values was calculated to be R2 = 0.98.
