WebUse GEE when you're interested in uncovering the population average effect of a covariate vs. the individual specific effect. These two things are only equivalent in linear models, but not in non-linear (e.g. logistic). To see this, take, for example the random effects logistic model of the j 'th observation of the i 'th subject, Y i j; For binary outcomes yi and the logit link function g(·), the model (1) is a logistic regression model with random effects. In a meta-analysis, the study effects correspond to the intercept, and the treatment effect to the slope of treatment/control indicator in the logistic regression; the log … See more Procedure rma.glmm in the R package metafor can be used to fit four of the models discussed in this section: FIM2, RIM2, NCHGN and ABNM (R code is given in Additional file 1).

The estimators … See more The simulations used the following configurations of the parameters. The number of studies was K=(3,5,10,30); the sample sizes in each arm across K studies were n=(50,100,250,1000); the between-study variance was … See more
