Design Based on Intra-Class Correlation Coefficients
Problem statement: Reliability studies are concerned with the study of “consistency” or “repeatability” of measurements. Often times (but not always) the reliability coefficients are Intra-class Correlation Coefficients (ICC). Depending on the design or the conceptual intent of the study there are three types of intra-class correlation coefficients, termed intra-class correlation coefficients C...

15 صفحه اولReliability analysis: Calculate and Compare Intra-class Correlation Coefficients (ICC) in SAS
Reliability studies are widely used to assess the measurement reproducibility of human observers, laboratory assays or diagnostic tests. For quantitative measures, intra-class correlation coefficient (ICC) is the principal measurement of reliability. In this paper, a SAS macro is provided to calculate the ICC and its confidence limits. The application of the macro is demonstrated in a clinical ...
