Abstract:
When there are two alternative random-effect models leading to the same marginal model, inferences from one model can be used
for the other model. We illustrate how a likelihood method for fitting models with independent random effects can be applied
to seemingly very different models with correlated random effects. We also discuss some merits of using these alternative
models.
