Engineering statistics combines engineering and statistics:〔〔〔Hogg, Robert V. and Ledolter, J. (1992). ''Applied Statistics for Engineers and Physical Scientists''. Macmillan, New York.〕〔Walpole, Ronald; Myers, Raymond; Ye, Keying. ''Probability and Statistics for Engineers and Scientists''. Pearson Education, 2002, 7th edition, pg. 237〕 # Design of Experiments (DOE) is a methodology for formulating scientific and engineering problems using statistical models. The protocol specifies a randomization procedure for the experiment and specifies the primary data-analysis, particularly in hypothesis testing. In a secondary analysis, the statistical analyst further examines the data to suggest other questions and to help plan future experiments. In engineering applications, the goal is often to optimize a process or product, rather than to subject a scientific hypothesis to test of its predictive adequacy.〔Box, G. E., Hunter,W.G., Hunter, J.S., Hunter,W.G., "Statistics for Experimenters: Design, Innovation, and Discovery", 2nd Edition, Wiley, 2005, ISBN 0-471-71813-0〕〔 The use of optimal (or near optimal) designs reduces the cost of experimentation.〔 # Quality control and process control use statistics as a tool to manage conformance to specifications of manufacturing processes and their products.〔〔〔 # Time and methods engineering use statistics to study repetitive operations in manufacturing in order to set standards and find optimum (in some sense) manufacturing procedures. # Reliability engineering which measures the ability of a system to perform for its intended function (and time) and has tools for improving performance.〔〔Nelson, Wayne B., (2004), ''Accelerated Testing - Statistical Models, Test Plans, and Data Analysis'', John Wiley & Sons, New York, ISBN 0-471-69736-2〕〔LogoWynn〕 # Probabilistic design involving the use of probability in product and system design # System identification uses statistical methods to build mathematical models of dynamical systems from measured data. System identification also includes the optimal design of experiments for efficiently generating informative data for fitting such models.〔 〕 ==Notes== 〔 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「Engineering statistics」の詳細全文を読む スポンサード リンク
