Abstract
Analysis of a major multi-site epidemiologic study of heart disease ha s required estimation of the pairwise correlation of several measureme nts across sub-populations. Because the measurements from each sub-pop ulation were subject to sampling variability, the Pearson product mome nt estimator of these correlations produces biased estimates. This pap er proposes a model that takes into account within and between sub-pop ulation variation, provides algorithms for obtaining maximum likelihoo d estimates of these correlations and discusses several approaches for obtaining interval estimates.
