The Repeated and Random Statements in Mixed Models for …

WebThe core of mixed models is that they incorporate fixed and random effects. A fixed effect is a parameter that does not vary. For example, we may assume there is some true regression line in the population, \(\beta\), and we get some estimate of it, \(\hat{\beta}\). In contrast, random effects are parameters that are themselves random variables. WebWe can model this structure of the data, children clustering in families, using linear mixed effects models. In addition to estimating population means ( fixed effects) these models will also allow us to estimate how average family heights vary around these population means ( random effects).
