Abstract

In medical and other related sciences, the clinical or experimental measurements obtained from multiple evaluators usually serve as a basis for diagnostic, prognostic, therapeutic, and performance evaluations. Thus, it is important to assess interevaluator agreement. The measurement scale can be continuous, binary, nominal, or ordinal. In this article, we review some commonly used approaches for both continuous and categorical outcomes.
