此m文件返回有用的残差缩放,即预测误差平方和(PRESS)。 要计算 PRESS,请选择一个观察值 i。 将回归模型拟合到剩余的 n-1 个观测值,并使用此方程来预测保留的观测值 y_i。 用 ye_(i) 表示这个预测值,我们可以找到点 i 的预测误差为 e_(i)=y_i - ye_(i)。 预测误差通常称为第 i 个 PRESS 残差。 对于每个观测值 i = 1,2,...,n 重复此过程,生成一组 n 个 PRESS 残差 e_(1),e_(2),...,e_(n)。 然后将 PRESS 统计量定义为 n 个 PRESS 残差的平方和,如下所示, PRESS = i_Sum_n e_(i)^2 = i_Sum_n [y_i - ye_(i)]^2 因此,PRESS 使用 n-1 个观测的这种可能子集作为估计数据集,并且每个观测依次用于形成预测数据集。 在构建这个 m 文件时

Elasticity is concerned with determining the strength and load carrying ability of engineering structures including buildings, bridges, cars, planes, and thousands of machine parts that most of us never see. It is especially important in the fields of mechanical, civil, aeronautical and materials engineering. Elasticity: Theory, Applications and Numerics 2e provides a concise and organized presentation and development of the theory of elasticity, moving from solution methodologies, formulations and strategies into applications of contemporary interest, including fracture mechanics, anisotropic/composite materials, micromechanics and computational methods. Developed as a text for a one or two-semester graduate elasticity course, this new edition is the only elasticity text to provide coverage in the new area of non-homogenous, or graded, materal behavior. End of chapter exercises throughout the book are fully incorporated with the use of MATLAB software. Key Features: * Provides a thorough yet concise introduction to general elastic theory and behavior * Demonstrates numerous applications in areas of contemporary interest including fracture mechanics, anisotropic/composite and graded materials, micromechanics, and computational methods * The only current elasticity text to incorporate MATLAB into its extensive end-of-chapter exercises * The book's organization makes it well-suited for a one or two semester course in elastictiy Features New to the Second Edition: * First elasticity text to offer a chapter on non-homogenous, or graded, material behavior * New appendix on review of undergraduate mechanics of materials theory to make the text more self-contained * 355 end of chapter exercises - 30% NEW to this edition
