Intra-class correlation coefficient(ICC)is increasingly being used in various fields of natural science and social science.Unfortunately,there's inadequate understanding of its definition and estimation methods in the application.It's very name origins from its classical definition,in which a pair-wise...
Definition The intraclass correlation coefficient is a measure of the correlation between individuals clustered within the same context. It is the proportion of the total unexplained variation in an outcome that is attributable to differences between the contexts. ...
The test theorist's definition of reliability is argued to conflict with intuitive notions of this concept. Sensitivity coefficient is proposed as a more appropriate term for the classical reliability coefficient.DavidComputationalG.ComputationalWastell...

assessment of consistency or reproducibility of quantitative measurements made by different observers measuring the same quantity. Early ICC definition: unbiased but complex formula The earliest work on intraclass correlations focused on the case of paired measurements, and the first intraclass correlation ...
Intraclass correlation coefficient (ICC) is a widely used reliability index in test-retest, intrarater, and interrater reliability analyses. This article introduces the basic concept of ICC in the content of reliability analysis. There are 10 forms of ICCs. Because each form involves distinct assump...

We propose a Bayesian test that allows the incorporation of previous information on the variance components used in the definition of the intraclass correlation coefficients and may be generalized to situations where normality does not hold. We develop computational algorithms to implement the proposed ...
