Abstract

To combine the information from several laboratories to output a representative value chi(sub r) and its probability distribution function is the main aim of an inter-comparison in Metrology. Here, the proposed procedure identifies a simple model for this probability function, by taking into account only the probability interval estimates as a measure of the uncertainty in each laboratory. A mixture density model is chosen to characterize the stochastic variability of the inter-comparison population considered as a whole. The bootstrap method is applied to approximate the distribution function of the comparison output in an automatic way.<br />The original document contains color images.
