Partial aliasing

When a regular design is used, any two factorial effects (main effects or interactions) are either orthogonal or are completely aliased. Partial aliasing of factorial effects makes the alias structures of nonregular designs much more complex (see Chapter 8 for information on the difficulties in the analysis when complex aliasing is present), but it also leads to some superior projection properties.
