Question

Refer to Example 8.1.
In example
a. For the model yij = μ + τ1 + εij, what are the values of t, n1, n2, and n3?
b. Using the observed data, provide estimates of μ, τ1, τ2, τ3, and s without the constraint τ2 = 0.
c. Using the observed data, provide estimates of μ, τ1, τ2, τ3, and s with the constraint τ3 = 0.
d. Compare the differences in the two sets of estimates produced in parts (b) and (c). This illustrates the importance of knowing what constraints are imposed by software programs when estimates are contained in the output of an analysis.
