     A Tecator Infratec Food and Feed Analyzer working in the
     wavelength range 850 - 1050 nm by the Near Infrared Transmission
     (NIT) principle was used to collect data on samples of finely
     chopped pure meat. 215 samples were measured. For each sample, the
     fat content was measured along with a 100 channel spectrum of
     absorbances. Since determining the fat content via analytical
     chemistry is time consuming we would like to build a model to
     predict the fat content of new samples using the 100 absorbances
     which can be measured more easily.
