Linear Mixed Effects Models Linear Mixed Effects models are used for regression analyses involving dependent data. Such data arise when working with longitudinal and other study designs in which multiple observations are made on each subject. Two specific mixed effects models are ?random intercepts models?, where all responses in a single group are additively shifted by a value that is specific to the group, and ?random slopes models?, where the values follow a mean trajectory that is linear in
