CORRECTIONS AND INPUT QUANTITIES IN GUM-COMPLIANT MODELS

F. Pavese

Abstract

The <i>Guide to the expression of uncertainty in measurement</i> (GUM) requires, "<i>that the results of a measurement have been corrected for all recognised significant systematic effects and that every effort has been made to identify such effects</i>" (3.2.4), before the issue of evaluating their uncertainty is tackled. In addition, the GUM also requires that a model is used, expressing the functional dependence of the measurand on the identified input quantities. The paper discusses the inter-relations between the so-defined two sets of influence quantities and proposes to unify their treatment.
