Abstract

  The talk discusses the ideas of generalized resolution and minimum aberration in experimental design. The approach is informal, mainly through examples. I first review the criteria of resolution and minimum aberration associated with regular fractional factorial designs, and then examine how these criteria can be generalized to non regular fractional factorial designs. Two key ideas are involved in this process of generalization. One is that we would like a design to have good projection properties, and the other is that a good design should be robust in some ways. As it turns out, the criteria of generalized resolution and minimum aberration do just that.
