Approximate vs. predicted ETV-H concentrations in test set samples obtained by the best performance PLS models (baseline correction and the SNV method for data pretreatment in the wave number range of 1350–1700 cm−1). Approximate ETV-H concentration referred to the approximate value of the real ETV-H concentration.
