第一类曲线积分 设一条具有质量的空间曲线 L 上任一点 (, ,) x y z 处的线密度为 ρ (, ,) x y z 。将 L 分成 n 个小曲线段 Li = \,,2,1( ni ),并在 Li 上任取一点 ),,(ξ η ζ iii ,那么当每个Li的长度Δ si 都很小时,Li的质量就近似地等于 iiii ρ ξ η ζ ),,( Δs ,于是整条L的质量就近似地等于
Ch. 20 Processes with Deterministic Trends 1 Traditional Asymptotic Results of OlS Suppose a linear regression model with stochastic regressor given by Y=x!3+e,t=1,2,…,T,;B∈R or in matrix form y=xB+E We are interested in the asymptotic properties such as consistency and limiting
Exercises Linear equations for the consumption and saving schedule take the general form C=a + bY and S=-a+(1-b)Y, where C, S and Y are consumption, saving and national income respectively. (1) Use the given data to develop specific numerical values for the consumption and saving equations. Write the using these values
