Supervised sparse partial least square discriminant analysis (sPLS-DA, top) and orthogonal projections to latent structures discriminant analysis (OPLS-DA, bottom) score plots of two data matrixes obtained with the OIV-MA-AS316-01 acquisition method: full ¹H-chemical shift binning (right) and signal bucketing of exclusively aromatic signals from 5.5-10 ppm of proton chemical shift range (left). Both signal bucketing strategies are highlighted in the middle of the figure. MSA score plots model discriminant fingerprints related to wines’ geographical origin, assigning red T2 Hotelling’s ellipse and scores to Baja California, black T2 Hotelling’s ellipse and scores to Coahuila and blue T2 Hotelling’s ellipse and scores to Queretaro samples, in agreement with country’s colour map.
