Difference between mean support vector spectra for (a) North East England (+ coefficients) and North West England (− coefficients), (b) North East England (+ coefficients) and West Scotland (− coefficients), (c) North West England (+ coefficients) and West Scotland (− coefficients). The main wavenumbers responsible for class differentiation between the three regions are labelled, and have been used to identify spectral markers
