We consider each term of the Fourier aeries representing the voltage as a single source. The equivalent impedance of the network at no is used to compute the current at that harmonic. XL(n) =noL and XC() =-1/noC The sum of these individual responses is the total response i

We select one node as a reference node and then define a voltage between each remaining node and the reference node

One CLRM assumption is: The model used in empirical analysis is \correctly specified\

Definition (1) Econometrics: economic measurement. (2) Econometrics: the social science in which the tools of economic theory, mathematics, and statistical inference are applied to the analysis of economic phenomena. (3) Econometrics: the result of a certain outlook on the role of economics, consists of the application of mathematical statistics to economic data to lend

在§1-7我们讲了某点的应力随所选截面方向改变而改变。过一点各方向 截面上应力矢量的集合称为该点的应力状态。但怎样描述一点的应力情 况—一点的应力状态? 我们可以用三对xxy)D取出一个 Oτ xyxz 通常叫:微单元体 ElemOM=垂直的平OM=OyT 点(M)的应力状态
