Models for Nested Factors Notation: Use subscript j(i) to denote that the factor indexed by j is nested in the factor indexed by i. Examples: 1. In the baby food example above, let A denote brand and B denote jar. Use index i = 1, 2, 3 for A and index j = 1, .. , 5 for B. Suppose there are r = 2 measurements
WebApr 8, 2024 · An experimental design in which the variables have an implicit hierarchy. For example, a hospital has two wings (I and II). Patients in wing I are randomly assigned to either consultant A or consultant B. Patients in wing II are randomly assigned to either consultant C or consultant D. Thus consultants A and B are nested within the wing I ... 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.
