WebAbstract. Consider an experiment with two factors A and B where the levels of B are nested within the levels of A. Assume that there are a levels of A and within the i th level of A there are b i levels of B and n ij observations are taken at the j th level of B. The model for this design is known as the unbalanced two-way nested classification.
