Single-Facet Designs, single facet, usually referred to as an item facet. Also, it is usually assumed that the population consists of persons. For a single-faceted universe, there are two designs that might be employed in a G study: the . × . or the .:. design, where the letter . is used to index persons (or examinees),

Unbalanced random effects designs are the subject of this chapter. Unbalanced mixed effects designs are treated using multivariate generaliz

In multivariate generalizability theory, each object of measurement has multiple universe scores, each of which is associated with a condition of one or more fixed facets, and ther
