Table 8.

Type III contrast weights derived from Doolittle factorization of X′X in the example unbalanced dataset.

μ α1 α2 β1 β2 γ11 γ12 γ21 γ22
Constant 1 0.5 0.5 0.5 0.5 0.25 0.25 0.25 0.25
A 0 1 −1 0 0 0.5 0.5 −0.5 −0.5
B 0 0 0 1 −1 0.5 −0.5 0.5 −0.5
A × B 0 0 0 0 0 1 −1 −1 1

Here the weights are derived after reduction of X to unique rows.
