"NettetIf you’re in a field where mixed models are more familiar and most readers will understand them, you’ll need to give enough detail that someone who understands mixed models could evaluate the approach. This means you will need to say which random effects you included and which covariance structure you chose. " - Linear mixed-effects model analysis

NettetIn statistics, a fixed effects model is a statistical model in which the model parameters are fixed or non-random quantities. This is in contrast to random effects models and mixed models in which all or some of the model parameters are random variables.
