These allow you to select the fixed effects and/or the random effects. The marginal prediction integrates out the random effects and is what a GEE marginal model produces. From what I've read, the marginal effects seem to be less desirable than the fixed effects from an lme or a generalized lme. But I would still like to compute them for comparison.
