CONSISTENCY MEASURES FOR PEER-TO-PEER COMPARISONS

A. G. Steele, R. J. Douglas

Abstract

This talk summarizes statistical approaches to consistency analysis using key comparison data, including conventional mediated testing relative to the inverse variance weighted mean, extensions of this chi-squared methodology to accommodate finite degrees of freedom in the uncertainty claims, and a fully bilateral approach that avoids invocation of any key comparison reference value.
