Software provides statistical design of experiments.
Press Release Summary:
Suited for engineers, researchers, quality professionals, and Six Sigma practitioners, Design-Expert v7.0 enables users to identify ideal process settings and find optimal product formulations. Minimum-run 2-level factorial designs let users screen for main effects with least number of experimental runs. Response Surface Methods graphics offer graduated or banded contour and 3D surface plots, while crosshairs window allows responses to be predicted at any place on response surface plot.
Original Press Release:
Make Breakthrough Improvements and Reduce Costs With New Design-Expert® 7.0 Software for DOE!
Minneapolis, MN (March 3, 2006)-Stat-Ease, Inc. announces the release of Design-Expert® 7.0 software for statistical design of experiments (DOE). This major new release is the perfect tool for engineers, researchers, quality professionals, Six Sigma practitioners, or other experimenters. With Design-Expert 7.0 (DX7) software users can make discoveries that lead to breakthrough improvements in product quality and process efficiency, resulting in more sales, greater customer satisfaction, and reduced costs. DX7 makes it easy to screen for important factors, identify ideal process settings, and find optimal product formulations.
Intuitive enough for beginners to use, but with plenty of power for statisticians, DX7 offers dozens of new features for design and analysis of experiments. Minimum-run (Min-Run) two-level factorial designs allow users to screen for main effects with the least number of experimental runs. New analysis tools include the Pareto chart of effects, which allows users to easily see the vital few effects relative to the trivial many. For response surface methods (RSM), central composite designs (CCDs) based on a Min-Run core are very efficient for a larger numbers of factors. Mixture-in-mixture designs are available for sophisticated experiments involving separate formulations that may interact.
Updated RSM graphics offer full-color graduated or banded contour and 3D surface plots. Lollipop points on the 3D surface graphs show where actual responses were collected. The new crosshairs window allows responses to be predicted at any place on the response surface plot. Improvements to the user interface include a new Screen Tips button with context-sensitive help, tutorial movies, and related internet links. Additional features include design creation tools, enhanced design augmentation ability, analysis capabilities, diagnostic capabilities, more improvements to the user interface, options for design evaluation, and new import/export tools. For more information on DX7 features, please visit www.statease.com/dx7descr.html.
Design-Expert 7.0 software, which retails for $995, comes with a printed Getting Started guide and many easy-to-follow tutorials in Adobe PDF format. Download a free 45-day trial version at www.statease.com. Single-user perpetual and annual network licenses are available. Stat-Ease supports software users with free technical support, as well as access to statistical consultants who are experts on design of experiments.
