1. A method for determining a property of interest of a test sample by utilizing a plurality of samples, each having a known value of the property of interest, comprising:

  • (a) subjecting each sample in the plurality of samples to a known light energy and collecting a corresponding spectrum for each such sample;

    (b) grouping the samples in the plurality of samples into a plurality of subsets;

    (c) determining a model for each such subset from the corresponding spectra of the samples in such subset;

    (d) selecting a group of models from the models determined for the each of the subsets based on a predetermined criterion;

    (e) retaining a subset of models from the group of models having residuals that are least correlated to one another; and

    (f) determining a composite model from the retained models to determine the property of interest of the test sample.
