Fig. 1From: Risk prediction in multicentre studies when there is confounding by cluster or informative cluster sizeComparison of the different fitting methods (GLMM, IEE, GEE with exchangeable correlation) for the Basic model, under different assumptions about the presence of CBC and ICS. ICC = 0.2. Performance measures from top left to bottom right: Calibration Intercept, Calibration slope, Root Predictive MSE and C-Statistic. Conditional (left Panel) and Marginal (right panel) predictions are shown for each measureBack to article page
