Processing by GA-LDA of the ATR-FTIR and Raman spectral datasets for categories: 1983–1984 and 2012–2013.

(A) Seventeen wavenumbers selected by GA-LDA model for the ATR-FTIR spectral dataset. (B) Graph representing the power calculation used to identify the optimum number of wavelengths to be used for SPA. (C) Scores (DF1 × DF2) plot calculated by using the variables selected by GA-LDA from ATR-FTIR spectra obtained from prostate tissues segregated into seven classes. (D) Fourteen wavenumbers selected by GA-LDA model for the Raman spectral dataset. (E) Graph representing the power calculation used to identify the optimum number of wavelengths to be used for SPA. (F) Scores (DF1 × DF2) plot calculated by using the variables selected by GA-LDA.
