1. A method of identifying one or more informative subsets of frequency ranges of an NIR spectrum for evaluating a biological sample, the method comprising performing a Nuclear Magnetic Resonance (NMR) analysis on a biological sample to obtain an NMR spectrum, performing a Near Infrared Spectroscopy (NIR) analysis on the biological sample to obtain an NIR spectrum, and obtaining one or more informative subsets of NIR frequency ranges of the NIR spectrum by performing a data fusion analysis of the NMR spectrum with the NIR spectrum.
