Application of Bayesian model averaging using a fixed effects model with linear drift for the analysis of key comparison CCM.P-K12

• In this paper, we extend a recently proposed procedure for the analysis of key comparison data to the case where the traveling standard shows a linear drift. The procedure is based on a fixed effects model and assumes that a certain number of the laboratories measure without bias. The analysis is carried out by applying Bayesian model averaging to all possible different models, each assuming zero biases for a different subset of laboratories. The method is applied to the key comparison CCM.P-K12.
