Abstract
Abstract Three nonparametric measures of intraclass correlation based on the notion of concordance are considered. Their unbiased estimators and nonparametric tests based on the estimators are studied and it is shown that an analogue of the Kendall's tau provides small variance estimator and relatively powerful test. Furthermore, the approximate variance of the estimator is given when the correlation is small in the normal model.

The maximum likelihood estimators of beta, sigma2, and rho when one observes N pairs (Xi, Yi) are developed typically in biological problems where one samples clusters of related organisms.
