Set up hypothesis using linear contrasts
| Ho | L | ||||||||
| Effects | Mean | Dg1 | Dg2 | Rg1 | Rg2 | (DR)g11 | (DR)g12 | (DR)g21 | (DR)g22 |
| (DR)gij = 0 | (μ21 - μ11) - (μ22 - μ12) = 0 | 0 | 0 | 0 | 0 | -1 | 1 | 1 | -1 |
| Dgi = 0 | (μ11 + μ12) - (μ21 + μ22) = 0 | 2 | -2 | 0 | 0 | 1 | 1 | -1 | -1 |
| Rgj = 0 | (μ11 + μ21) - (μ12 + μ22) = 0 | 0 | 0 | 2 | -2 | 1 | -1 | 1 | -1 |
The hypothesis in terms of model parameters and means were listed. The coefficients for the model parameters of the linear contrasts were determined for the corresponding hypotheses.
