Fig. 4

(a) Overall 110 NIR spectra for temperatures of 30, 40, 50, 60, and 70 C are shown. Illustration of (b) the regression vector \(\hat {\beta }_{OPLSb}\) and (c) the empirical null distribution of the realized \(\hat {\beta }_{OPLSb,i}\) are shown for the NIR spectra. The wavelength ranges of the selected variables were from 960 to 970 nm (x381 to x391) and from 1049 to 1060 nm (x470 to x481)
