title: Inferences concerning a common intraclass correlation coefficient.
abstract: The maximum likelihood estimator, rhoM, of a common intraclass correlation, rho, is derived in two independent samples drawn from multivariate normal populations. A likelihood ratio statistic for testing the assumption of a common rho is also derived and examples are given. Comparisons are made with a procedure based on Fisher's transformation.
