Binary clustering coefficient

WebDec 8, 2024 · Generalized estimating equations are commonly used to fit logistic regression models to clustered binary data from cluster randomized trials. A commonly used correlation structure assumes that the intracluster correlation coefficient does not vary by treatment arm or other covariates, but the consequences of this assumption are … Websurement of the extent to which the observations in a cluster or within an individual are correlated is often of interest. In this note, we discuss measures of intra-class correlation in random-effects models for binary outcomes. We start with the classical definition of intra-class correlation for continuous data (Longford 1993,Chapter 2).
