Dynamic Localized SNV, Peak SNV, and Partial Peak SNV: Novel Standardization Methods for Preprocessing of Spectroscopic Data Used in Predictive Modeling

Figure 10

Box-and-whisker plot representation of the root-mean-squared error of prediction of the cross validation strategy for the phenolic antioxidant compound of ATF B. In (a), the RMSEP values for the transmission spectra are shown, and in (b), the RMSEP values for the absorbance spectra are shown. Boxplot (1) is without standardization, (2) is with a single SNV transformation on the full spectrum, (3) is with optimized LSNV, (4) is with optimized Dynamic DLSNV, (5) is with optimized PSNV, and (6) is with optimized PPSNV.
