Popis:	102 In clinical studies, we concern with assessing agreement between different observers or methods. The concordance correlation coefficient (CCC) and intraclass correlation coefficient (ICC) are the two popular indices for measuring agreement on continuous data. In linear mixed models, the equivalence between ICC and CCC can be established through variance components (VC). In this thesis, we focus on estimating CCC using VC and U-statistics approaches. Simulation studies are conducted to compare the performance of VC and U-statistics approaches with and without explanatory variables. An application of conformity between two optometric devices is used for illustration.
