In the two factor ANOVA models described elsewhere on this website, the factors are fully crossed; i.e. each level i in Factor A is paired with every level j in Factor B. In this section we describe nested (or hierarchical) models in which each level i in Factor A is paired with only one level j in Factor B.
We will assume that we have a completely balanced design. This means that for each level i in Factor A and level j in Factor B the number of elements nij are equal (say to m), and for each level i in Factor A the number of levels in B are the same.
