Design-Expert 6.0 software for design of experiments (DOE) offers a number of improvements over version 5.0. Additional experimental designs and analysis capabilities now allow for combinations of mixture, process, and categorical factors. A new design option creates full-factorials or d-optimal subsets for multilevel categorical factors. The interface has also been sharpened with progressive toolbars for statistical analysis. New design-building wizards, optimization features, interactive 2-D graphics, and rotatable 3-D plots reportedly simplify the DOE process. Design-Expert 6.0 costs $995, but a free trial version can be downloaded from Stat-Ease?s website (below) for the undecided.
