The Norwegian Research Council finances a Ph.D.-student in this field. The group has done a lot of work in the field of multivariate regression and calibration . Methods like PLS and PCR are central here. Spectroscopic measurements, like the NIR, are often a speedy alternative to slower and more expensive measurements. The spectroscopic measurements can be used to predict a variety of other features, like particle size distributions, concentrations, etc.
Spectroscopic measurements are of course just an example of the area of use.
