A graphical comparison of supersaturated designs

The search of construction methods for a "good" supersaturated design has received a great deal of attention in recent years. Many single-valued criteria have been proposed for comparison purposes. In this paper, we propose/review three criteria based on the information matrix of a projective design and provide two graphical methods for comparing different types of supersaturated designs: the line plot and the boxplot methods. Four different construction methods are compared using the proposed graphical techniques. These construction methods were proposed by Booth and Cox (1962), Lin (1993), Wu (1993) and Lin (1995). A thorough discussion on the proposed graphical techniques is given.
