计量经济学stata上机教程

计量经济学stata上机教程2014计量经济学上机教程1Stata操作基础主要内容:1. Stata的特点与功能2. Stata的界面管理3. Stata的命令语法4. 数据处理5. 统计描述、制图与输出结果6. log文档与do文档7. 常用函数8. Stata的帮助系统与学习资源9. 课后练习1. Stata的特点与功能, 将统计功能与计量分析完整地结合起来。

不仅可以实现诸多统计分析方法，比如描述统计、假设检验、方差分析、主成分分析等，而且可以实现多种计量经济模型的估计和检验，包括经典单方程回归模型、方程组模型、微观数据模型(离散选择模型、计数模型、截断模型、归并模型等)、时间序列数据模型(ARMA、VAR、GARCH等)以及面板数据分析。

, 强大的数据处理功能。

, 精致的作图功能。

, 丰富的网络资源。

Stata 12有各种版本，其中尤以SE(特殊版)最为常用。

用户可以在命令栏中输入about命令查看所安装的版本信息。

横河CS3000功能块说明<Toc> <Ind> <D1. Regulatory Control> D1-1IM 33S01B30-01ED1. Regulatory Control调整控制The regulatory control performs control computation processing using analog process values for process monitor and process control. The function blocks that provide the regulatory control function are referred as “regulatory control blocks.”调整控制是利用过程监控及过程控制中的模拟过程量来进行控制计算处理的。

This chapter presents a detailed description of the function of each of the regulatory control blocks, excluding the Foundation Fieldbus faceplate block. 这章将逐个介绍每个调整控制块的功能，包括基金会现场总线的面板功能块。

SEE ALSO参阅For details on the Foundation Fieldbus faceplate blocks, see chapter A2, “Overview of FF Faceplate Blocks” in the Foundation Fieldbus Reference (IM33Y05P10-01E).想了解基金会现场总线面板功能块的详细情况，请参照关于FF部分的A2章节“FF面板功能块的概述”■Regulatory Control Positioning ¡调整控制的配置The regulatory control is one of the basic controls in the FCS and performs control computation processing to monitor and control processes. The function blocks that perform the this regulatory control are referred as “regulatory control blocks.”调整控制是FCS的一个基本控制单元，执行过程监控的控制计算处理。

统计学专业名词(中英对照)

统计学专业名词·中英对照我大学毕业已经多年，这些年来，越发感到外刊的重要性。

读懂外刊要有不错的英语功底，同时，还需要掌握一定的专业词汇。

掌握足够的专业词汇，在国内外期刊的阅读和写作中会游刃有余。

在此小结，按首字母顺序排列。

这些词汇的来源，一是专业书籍，二是网上查找，再一个是比较重要的期刊。

当然，这些仅是常用专业词汇的一部分，并且由于个人精力、文献查阅的限制，难免有不足和错误之处，希望读者批评指出。

1. A random sample of two observations is taken from a population that is normally distributed with a mean of 100 and a standard deviation of 5. Which of the following is closest to the probability that the sum of the two observations is greater than 221？A. 0.0015B. 0.0250C. 0.0500D. 0.4500E. 0.9985Answer ：AAnalysis ：本题考查正态变量大于某个数的概率。

P(X>221) = P(Z>24.2) = 0.00152. Let X represent a random variable whose distribution is normal, with a mean of 100 and a standard deviation of 10. Which of the following is equivalent to P(X >115)?A. P(x < 115)B. P(x <= 115)C. P(x < 85)D. P(85 < x < 115)E. 1 - P(x < 85) Answer ：CAnalysis ：本题考查正态分布的对称性。

均值为100，那么和115对称的就是100-15 = 85。

3. Suppose that public opinion in a large city is 65 percent in favor of increasing taxes to support the public school system and 35 percent against such an increase. If a random sample of 500 people from this city are interviewed, what is the approximate probability that more than 200 of these people will be against increasing taxes?A.200300500(0.65)(0.35)200⎛⎫ ⎪⎝⎭B.200300500(0.35)(0.65)200⎛⎫ ⎪⎝⎭C.P z ⎛⎫⎪ > ⎝D.P z ⎛⎫ ⎪ > ⎝E.P z ⎛⎫⎪ > ⎝Answer ：E Analysis ：本题考查二项用正态模拟。
