Marginal model
WebAug 16, 2016 · For regressions with correlated, non-normal outcomes, two main approaches are used: conditional and marginal modelling. The former leads to generalized linear mixed models (GLMMs), while the latter are estimated using generalized estimating equations (GEEs), or marginalized multilevel regression models. WebA marginal model accounts for the correlation within each cluster. A conditional model also takes into account the correlation within each cluster. My questions are: Does a marginal model models main effects across a population whereas a conditional model models main effects within a cluster and across a population?
