Stat-Ease, Inc. is a privately held company producing statistical software in Minneapolis, Minnesota founded by Pat Whitcomb in 1982. The company currently has 14 employees. The company provides software packages for engineers and scientists using Design of experiments methods (DOE) for optimizing development of products and processes. It also provides DOE training and consulting services. ==History== Stat-Ease was founded by Pat Whitcomb while at General Mills in 1982. He later brought in two of his General Mills colleagues—Tryg Helseth as Programmer and Mark Anderson as Business Manager. Whitcomb and Anderson are Principals of the company today.〔“(Homegrown Software a Trans-Atlantic Hit ),” Chemical Engineering and Materials Science News, Spring 2001.〕 The company sold its first software in June 1985. Sales took off in 1987 when the software was described as “incredibly easy to use” in a review of DOE software.〔Nachtsheim, "Tools for Computer Aided Experiments,” Journal of Quality Technology, Vo. 19, No. 3, July 1987. pp 132-160.〕 In 1988, the company released its first version of Design-Expert software, which provided the tools for response surface methods (RSM) for process optimization. This package complemented Design-Ease, which handled factorial designs, and also provided statistical tools for optimizing mixtures in the chemical process industries. In 1996, the firm added the features of Design-Ease into Design-Expert version 5 and translated it from DOS to Windows. Both packages are still marketed today.〔Li He, (Design of Experiments Software ), The Chemical Information Network, July 17, 2003〕 In 1996, ''Forbes'' Magazine said the “new mantra” for process improvement is multivariate testing (MVT) and added: “A Minneapolis software firm, Stat-Ease, sells most of the software these MVT types use.”〔Rita Koselka, “The New Mantra: MVT," Forbes, March 11, 1996.〕 Felix Grant, reviewing Design-Expert version 7.1.3 in ''Scientific Computing Magazine'' said: “In a mature, well-established product which dominates its market, upgrades should be expected to reflect developing practice and display evolutionary growth rather than piling on attention-seeking gimmicks; and so it is here.... Core functions have been extended usefully... the design editor in Design-Expert (DX) has long been a strong point, providing a central cockpit from which to intuitively refine and test most aspects, but various new control features have now been added to the package, small in themselves but significantly enhancing productive control.”〔Felix Grant, “(Design Expert 7.1 ),” Scientific Computing World, October 2007.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stat-Ease」の詳細全文を読む スポンサード リンク
