Webb1 mars 2005 · The intraclass correlation coefficient (ICC) represents the proportion of the total variance that is accounted for by between-cluster rather than within-cluster variation. The ICC has been estimated from an analysis of variance of the outcome on cluster even when the outcome is binary [4], [5]. Webbnon-normal outcomes. Also, even when considered, models with dichotomous outcomes (e.g., pass/fail) are more often discussed than those with polytomous outcomes (e.g., …

Webb6 dec. 2024 · The ICC is the ratio of the between-cluster variance to the total variance in the outcome [ 20 ]. It provides a quantitative measure of the amount of heterogeneity across clusters [ 14 ]. With binary data, estimating the ICC from a GLMM is possible, though more complicated [ 14 – 16 ].
