Table 2. Classification results for Raman prediction of the two groups using a principal component analysis-linear discriminant analysis (PCA-LDA) algorithm, where 80% and 20% of the total data set were used for the training and test groups, respectively. The spectra were analyzed by linear discriminant analysis (LDA) using the first eight principal components.
