Population-averaged model
WebApr 1, 1991 · It is shown that, unlike models for correlation Gaussian outcomes, the parameters of the cluster-specific and population-averaged models for correlated binary data describe different types of effects of the covariates on the response probabilities. Summary Clustered or correlated samples of binary responses arise frequently in practice … WebResults: Pediatricians had higher predicted satisfaction ratings than PCPs (total effect = 4.8, 95% CI 3.7–5.9), with population-averaged mean of 82.2 (0.54) vs 77.4 (0.13). The direct effect was 3.9 (2.8–5.0) and the indirect effect was 0.9 (0.9–0.9), suggesting that part but not all of the total effect can be explained by pediatricians having decreased waiting/visit …

WebFeb 21, 2013 · This study proposes an estimator, which is based on a five-point Gauss−Hermite quadrature, for population-averaged predictions in the context of GLMM. The estimator was tested through Monte Carlo simulation and compared with a regular generalized linear model (GLM). The estimator was also applied to a real-world case … WebNov 16, 2024 · Stata estimates extensions to generalized linear models in which you can model the structure of the within-panel correlation.
