Unbalanced Random Effects Designs
To this point, our discussion of generalizability theory has been restricted to balanced designs. Doing so substantially decreases a number of statistical complexities, and even some conceptual ones. In practice, however, generalizability analyses with real data are often characterized by unbalanced designs. Unbalanced random effects designs are the subject of this chapter. Unbalanced mixed effects designs are treated using multivariate generalizability theory, which is discussed in Chapters 9 to 12.1 The discussion here of unbalanced random effects designs is relevant for both univariate and multivariate generalizability theory.
