E  Examples

The SuperMix program is used for mixed-effects models, also called multilevel, hierarchical, or random-effects models. These models can be used for the analysis of longitudinal data, where each individual may be measured at a different number of occasions. They can also be used for clustered data, for example, patients nested within clinics.

SuperMix fits mixed-effects models with continuous, count, ordinal, nominal, and survival outcome variables to nested data. SuperMix allows for up to three levels of nesting. Illustrative examples of these analyses are available in our manual.
