A classification model was built using principal
component analysis (PCA) and linear discriminant analysis (LDA). LDA with cross-validation showed that
the data fusion could achieve 78.5–86.7% correct classification (sensitivity), while those rates using
individual spectroscopies ranged from 42.2% to 70.4%. The results demonstrated that the fluorescence,
UV and visible spectroscopies complemented each other, yielding higher synergic effect.
