Empirical Modeling and Data Analysis for Engineers and Applied Scientists English | 25 July 2016 | ISBN: 3319327674 | 264 Pages This textbook teaches advanced undergraduate and first-year graduate students in Engineering and Applied Sciences to gather and analyze empirical observations (data) in order to aid in making design decisions. While science is about discovery, the primary paradigm of engineering and “applied science” is design. Scientists are in the discovery business and want, in general, to understand the natural world rather than to alter it. In contrast, engineers and applied scientists design products, processes, and solutions to problems. That said, statistics, as a discipline, is mostly oriented toward the discovery paradigm. Young engineers come out of their degree programs having taken courses such as “Statistics for Engineers and Scientists” without any clear idea as to how they can use statistical methods to help them design products or processes. Many seem to think that statistics is only useful for demonstrating that a device or process actually does what it was designed to do. Statistics courses emphasize creating predictive or classification models – predicting nature or classifying individuals, and statistics is often used to prove or disprove phenomena as opposed to aiding in the design of a product or process. In industry however, Chemical Engineers use designed experiments to optimize petroleum extraction; Manufacturing Engineers use experimental data to optimize machine operation; Industrial Engineers might use data to determine the optimal number of operators required in a manual assembly process. This text teaches engineering and applied science students to incorporate empirical investigation into such design processes.

动态危害 动态危害的目标是估计生存分析中的时变效应。 时变效应是通过状态空间模型估算的,其中状态系数遵循给定的随机游动。 使用状态空间模型的优势在于,您可以推断出最近观察到的时间段以外的时间。 有关更多详细信息,请参见ddhazard小插图。 。 粒子滤波和更平滑的方法可以比随机游走模型估计更通用的模型。 有关一些示例,请参见目录。 安装 您可以使用以下命令从github安装dynamichazard: # install.packages("remotes") remotes :: install_github( " boennecd/dynamichazard " ) 您还可以通过调用以下命令从CRAN下载该软件包: install.packages( " dynamichazard " ) 示例-ddhazard 我将使用JMbayes软件包中的aids数据集。 数据集
