Introductory Overview

The Variance Estimation and Precision module provides a comprehensive set of techniques for analyzing research designs that include both fixed and random effects. With this module, you can obtain estimates of variance components and use those estimated variance components to make precision statements while at the same time comparing fixed effects in the presence of multiple sources of variation. 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.
