Show affiliationsThe Mutual Recognition Arrangement (MRA) requires the calculation of unilateral degrees of equivalence (DoE), defined as the difference between a laboratory's measurement and a key comparison reference value (KCRV). The functional form of the KCRV has been a source of much debate, with most of the proposed solutions being based on a frequentist interpretation of probability. The focus of this article is on the case when the result of each laboratory's measurement is interpreted as a mean and standard deviation of a probability distribution of belief about a measurand. Bayesian statistical methods are best suited to deal with this situation and lead to interesting insights about the form of the KCRV and the DoE.
