  1. The table displays the optimal likelihood, the number of convergent runs (as selected by Akaike’s weights over 50 SAEM runs), the number of fixed and random effects, as well as the average \(\eta\)-shrinkage for each parameter (expressed as a percentage of the population variance) over the convergent runs for our models. For each model, we give the reference of the equation where it is defined.
