Patent ID: 7369952

Claim:
A system to determine for a sample the extent to which it belongs to a class so that a diagnostic indication of a health state can be given, comprising: a memory unit for storing the signals of an electromagnetic spectrum obtained by a detector, said signals being generated by measuring an unknown sample; an analyzer unit for (i) generating a sample parameter using a multivariate analytical method based on the signals of the electromagnetic spectrum and (ii) allocating the sample parameter to a data record calculated by interpolation between at least one part of a first data and at least one part of a second data, wherein the first and second data are allocated to a first and second class, respectively, the first data comprises a first parameter generated on the basis of electromagnetic spectra of known samples belonging to the first class using the multivariate analytical method so that a reliable allocation of samples to the first class on the basis of the first parameter is possible, and the second data comprises a second parameter generated on the basis of electromagnetic spectra of known samples belonging to the second class using the multivariate analytical method, so that a reliable allocation of samples to the second class is possible on the basis of the second parameter, and (iii) determining a proportion value for the sample parameter regarding at least a part of the data record, wherein the proportion value reflects a relation of the sample parameter to a class in such a way that it can be determined to what extent the unknown sample belongs to a class; and an output unit for display of the relation of a sample to a class.
