GLMMs can also be viewed as a natural extension of Mixed Linear Models citep{Pinheiro:2000}

There are a large number of models for maintenance of mechanical components in the literature. Most of them assume that effect of maintenance interventions as “good as new”.

cause a behavior. We know the relationship between hormones and behaviors is reciprocal. Higher levels of hormones increase the probability of certain behaviors, and certain behaviors increase the probability of change in hormones.
