Abstract:
A computer implemented method of normalizing at least two measurement methods, the method comprising:receiving data specifying measured values versus physical properties for samples evaluated by the measurement methods, wherein the data includes (i) at least two first sample data points which were obtained from a first sample analyzed with at least two of the measurement methods and (ii) at least two second sample data points which were obtained from a second sample analyzed with at least two of the measurement methods;assuming a value for the physical property of the first sample and assuming a value for the physical property of the second sample;for each of the measurement methods, assuming a mathematical form of a response curve describing the measured values as a function of the physical properties, wherein the forms of expression contain unknown parameter values; andsimultaneously solving for all the unknown parameter values and a correction factor for the value of the physical property of the second sample.
