Hi, According to Kneib & Greven (biometrika 2010) ? the corrected version of the conditional AIC was developed exactly with the goal of allowing for sensible model selection in mixed models. For the marginal AIC we did not find a proper correction, so we would in general not recommend this in its current form. ? ? We have recently developed an R package called cAIC4 (https://cran.r-project.org/web/packages/cAIC4/index.html) that should be a good starting point (also beyond Gaussian mixed effects models). ?

May I ask if you found any solution for this? Best, Mick ??[[alternative HTML version deleted]]
