Linear mixed models with skew-elliptical distributions: A Bayesian approach
TL;DR: A simple and robust Bayesian parametric approach that relaxes this assumption ofNormality of random effects and error terms by using a multivariate skew-elliptical distribution, which includes the SkeW-t, Skew-normal, t-Student, and Normal distributions as special cases and provides flexibility in capturing a broad range of non-normal and asymmetric behavior is presented.
