New Design-Expert® 7.1 Software for Design of Experiments (DOE)

Minneapolis, MN (May 2007)—Stat-Ease, Inc. announces the release of Design-Expert^® 7.1 software for design of experiments (DOE).  Sophisticated, yet user-friendly, this new release is a must for anyone who wants to uncover the sweet spot in their process, make a breakthrough improvement to their product, or find the optimal formulation.  Design-Expert 7.1 (DX7.1) is the perfect tool for engineers, researchers, quality professionals, Six Sigma practitioners, or other experimenters—easy enough for novices to use, but with the power that advanced users seek. 

DX7.1 includes a variety of innovative new features for the design and analysis of experiments.  All users will gain appreciation for the program’s upfront power calculation for factorial designs, which provides the probability of seeing a desired difference (the signal) in your measured response given the amount of noise in the process.  This knowledge could save an experimenter the embarrassment of pressing ahead with what will be a lost cause if there is excessive variability in the process and/or test. Statisticians will like the innovative fraction of design space (FDS) graph for design evaluation. It displays scaled prediction variance (SPV)—quite useful for comparing alternative designs.

The new version of Design-Expert displays grid lines on 3D graph back planes, which provide a good perspective on the varying height of a response surface.  The program also now saves graphs in a large number of different formats for use in presentations and publications.  In addition, DX7.1 can handle up to 50 factors for screening and response surface methods (RSM) via unique minimum-run design matrices.  For a complete list of DX7.1’s features, go to http://www.statease.com/dx71descr.html.
