Abstract
Statistical structure of the fraction of symmetrical factorial designs is investigated in some detail. In this paper, we show that the information matrix of a fractional factorial design is determined completely by its characteristic vector. We also give an explicit expression of the elements of the infomation matrix of the design derived from -symbol balanced arrays in terms of its indices.
