Variance Components and Mixed Model ANOVA/ANCOVA Introductory Overview - Summary

The Variance Components and Mixed Model ANOVA/ANCOVA module is a full-featured implementation of techniques for the analysis of models with random effects. Using the features in this module, you can easily analyze a variety of models containing random effects, obtain estimates of the contribution of the random factors to the variation on the dependent variables, and test the significance of the components of variance.

For examples of mixed model analyses in which variance components are estimated, see the Examples. For basic information on ANOVA in linear models, see also, Elementary concepts.
