By using the concept of conditional main effects (CMEs) to reparametrize the

3d space of two main effects A, B and their interaction AB, it is possible to

de-alias aliased two-factor interactions (2fis). An analysis method, called CME

Analysis, is developed in Section 5.5, which allows aliased 2fis in resolution

IV or III designs to be further studied. It can lead to the identification of more

parsimonious and better fitting models.
