Abstract
The problem of determining a consensus value and its uncertainty from the r esults of multiple methods or laboratories is discussed. Desirable criteria of a solution are presented. A solution motivated by the ISO Guide to the Expression of Uncertainty in Measurement (ISO GUM) is introduced and applie d in a detailed worked example. A Bayesian hierarchical model motivated by the proposed solution is presented and compared to the solution.
