Among the two-level nonregular designs the 12 run and the 20 run Plackett-Burman designs seem to be the ones that are used the most. The two-level nonregular 16 run designs seem to be forgotten even though they have attractive projection properties and, when the number of experimental factors is above 6, represent important alternatives to the regular designs. For various numbers of experimental factors these designs have been classified according to criteria like generalized minimum aberration and minimum aliasing. However they also have some hidden aliasing structure, that have not been pointed out so far, and which have to be taken into account when their analysis is performed. In this presentation we will focus on this hidden alias structure and ways to analyze these designs.
