Bayesian Approaches to Calculating a Reference Value in Key Comparison Experiments

Summary: [This abstract is based on the author's abstract.]International comparisons of measurements, called key comparisons, pose a statistical problem concerning the estimation of a reference value. The estimator can take many possible forms, but none have been accepted as a standard. It is argued here that a fully Bayesian approach to this problem is compatible with the current practice of metrology and can be used to construct models for the various properties and assumptions of these experiments.
