Variance Components and Mixed Model ANOVA/ANCOVA - Introductory Overview

The Variance Components and Mixed Model ANOVA/ANCOVA module provides a comprehensive set of techniques for analyzing research designs that include random effects; however, it is also well suited for analyzing large main effect designs (e.g., designs with more than 200 levels per factor), designs with many factors where the higher order interactions are not of interest, and analyses involving case weights. There are several modules in STATISTICA that will perform Analysis of Variance for factorial or specialized designs. For a discussion of these modules and the types of designs for which they are best suited refer to Methods for Analysis of Variance.
