It is traditionally assumed that the random effects in mixed models follow a multivariate normal distribution, making likelihood‐based inferences more feasible theoretically and computationally. However, this assumption does not necessarily hold in p... Read More about Diagnosing misspecification of the random-effects distribution in mixed models.
