A method and apparatus for non-invasively measuring a biological attribute such as the concentration of an analyte particularly a blood analyte in , tissue such as glucose. The method utilizes spectrographic techniques in conjunction with an improved subject tailored calibration model. In a calibration phase, calibration model data is modified to reduce or eliminate subject-specific attributes, resulting in a calibration data set modeling within subject physiological variation sample location, insertion variations, and instrument variation. In a prediction phase the prediction process is , tailored for each target subject separately using a minimal number of spectral measurements from …
