Claim 17:
18. A method of estimating a concentration of an analyte, the method comprising:
obtaining an in vivo estimation spectrum;
generating a plurality of noise detection models by varying a number of principal components based on in vivo spectra and the obtained in vivo estimation spectrum;
comparing the generated plurality of noise detection models with a plurality of concentration estimation models for each number of principal components, wherein each of the plurality of concentration estimation models uses a different number of principle components than another of the concentration estimation models;
extracting a noise spectrum and a concentration estimation model for use in estimating the concentration of the analyte based on the comparison;
updating the extracted concentration estimation model based on the extracted noise spectrum; and
estimating the concentration of the analyte by using the updated concentration estimation model and the obtained in vivo estimation spectrum,
wherein the extracting of the noise spectrum and the concentration estimation model for use in estimating the concentration of the analyte comprises:
determining a correlation coefficient for each number of principal components by comparing the generated plurality of noise detection models with the plurality of concentration estimation models for each number of principal components.
