Abstract:
1. A method for determining a reliability of a target measurement by combining reference measurement collections of at least three reference measurement systems into a weighted reference measurement collection, each reference measurement collection (RMC) including a plurality of corresponding sample measurements, each corresponding sample measurement having a measurement value of the same sample, the method comprising the steps of: for each possible RMC pairing, plotting corresponding measurement values to generate a plurality of data pairs; generating a best-fit line of the plurality of data pairs for each RMC pairing; calculating a residual for each data pair, each residual associated with each RMC of the RMC pairing to which the respective residual belongs; assigning a weight to each sample measurement for each RMC, wherein each weight is based on the residuals associated with a respective RMC to which the sample measurement belongs and favors a smaller residual more than a larger residual; for each respective sample measurement, generating a weighted reference measurement based on the measurement value for the respective sample measurement for each RMC and the weights of the respective sample measurement for each RMC; and comparing the weighted reference measurement with the target measurement to determine the reliability of the target measurement.
