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.
