Statistically-based performance characteristics in laboratory performance studies

Abstract

The International Harmonized Protocol for the Proficiency Testing of (Chemical) Analytical Laboratories (Thomson, M., and Wood, R., J. AOAC Int., 1993, 76, 926) lays down the minimum requirements for proficiency testing schemes. A prerequisite of statistically-based laboratory-performance characteristics is a suitable statistical model. A detailed investigation of statistical modelling, laboratory performance characteristics and quality limits is presented in this paper.
