应用回归分析第四版课后习题答案全何晓群刘文卿
实用回归分析第四版第一章回归分析概述1.3回归模型中随机误差项ε的意义是什么?答:ε为随机误差项,正是由于随机误差项的引入,才将变量间的关系描述为一个随机方程,使得我们可以借助随机数学方法研究y与x1,x2…..xp的关系,由于客观经济现象是错综复杂的,一种经济现象很难用有限个因素来准确说明,随机误差项可以概括表示由于人们的认识以及其他客观原因的局限而没有考虑的种种偶然因素。
1.4 线性回归模型的基本假设是什么?答:线性回归模型的基本假设有:1.解释变量x1.x2….xp是非随机的,观测值xi1.xi2…..xip是常数。
2.等方差及不相关的假定条件为{E(εi)=0 i=1,2…. Cov(εi,εj)={σ^23.正态分布的假定条件为相互独立。
4.样本容量的个数要多于解释变量的个数,即n>p.第二章一元线性回归分析思考与练习参考答案2.1一元线性回归有哪些基本假定?答:假设1、解释变量X是确定性变量,Y是随机变量;假设2、随机误差项ε具有零均值、同方差和不序列相关性:E(εi)=0 i=1,2, …,nVar (εi)=σ2i=1,2, …,nCov(εi,εj)=0 i≠j i,j= 1,2, …,n假设3、随机误差项ε与解释变量X之间不相关:Cov(X i, εi)=0 i=1,2, …,n假设4、ε服从零均值、同方差、零协方差的正态分布εi~N(0, σ2) i=1,2, …,n2.3 证明(2.27式),∑e i =0 ,∑e i X i=0 。

新编大学英语4课后习题答案完整版
新编大学英语4课后习题答案完整版《新编大学英语 4 课后习题答案完整版》在大学的英语学习中,《新编大学英语 4》是一门重要的课程。
课后习题对于巩固所学知识、检验学习效果起着关键作用。
下面为大家呈现一份完整的课后习题答案。
第一单元的课后习题主要围绕词汇、语法和阅读理解展开。
在词汇部分,需要我们准确理解单词的含义和用法。
例如,“accommodate”这个单词,不仅有“提供住宿”的意思,还有“容纳;适应”等含义。
在句子“The hotel can accommodate up to 500 guests”中,就是“容纳”的意思。
语法方面,重点考查了时态和语态的运用。
像过去完成时,在“By the time I got to the party, everyone had already left”这个句子中,“had already left”就体现了过去完成时,表示在过去某个时间点之前已经完成的动作。
阅读理解的题目则要求我们能够快速准确地获取文章中的关键信息,并理解作者的意图。
比如,有一篇文章讲述了现代科技对人们生活的影响,我们需要从文中找出支持或反对这种影响的观点和论据。
第二单元的习题在难度上有所提升。
词汇练习中出现了更多的近义词辨析,如“distinguish”和“differentiate”,这两个词都有“区分”的意思,但在用法和侧重点上有所不同。
语法部分,虚拟语气成为了重点。
“If I were you, I would take the job”这就是一个典型的虚拟语气句子,表示与现在事实相反的假设。
阅读理解的文章题材更加多样化,涵盖了文化、历史、科技等领域。
这就要求我们具备更广泛的知识背景和较强的理解能力。
第三单元的课后习题注重对语言综合运用能力的考查。
在词汇练习中,会有根据语境填写单词的题目,这需要我们对单词的含义和搭配有深入的理解。
比如,“The athlete's performance was ______ (remarkable),winning the gold medal”这里应该填写“remarkable”,表示“出色的”。

新编大学英语4课后习题答案完整版
新编大学英语4课后习题答案完整版首先是听力部分。
在听力练习中,重点考察了对各种场景下英语对话和短文的理解。
比如,有关于校园生活、学术讨论、社会现象等的话题。
对于听力理解题,关键是要抓住关键信息,包括人物关系、事件发生的时间地点、主要观点等。
以第一单元的听力练习为例,其中有一段关于学生社团活动的对话。
在这道题中,我们需要留意对话者提到的社团名称、活动内容以及参与的人员等。
通过仔细倾听和辨别,答案可能是“该社团将在周末举办一场义卖活动,旨在为贫困地区的儿童筹集资金”。
在口语部分,课后习题通常要求进行情景模拟、观点表达或者对话交流。
例如,有让学生讨论如何提高校园环境质量的话题。
这时候,我们可以从加强垃圾分类管理、增加绿化面积、倡导学生文明行为等方面进行阐述。
比如,“我认为可以在校园内设置更多的垃圾分类设施,并加强对学生的垃圾分类教育,让大家明白垃圾分类的重要性。
同时,学校可以组织志愿者活动,定期清理校园内的垃圾和杂物。
”阅读部分的习题形式多样,包括阅读理解、词汇理解、句子翻译等。
在阅读理解题中,要学会快速浏览文章,抓住主旨大意,然后仔细阅读题目,回到文章中寻找相关信息。
例如,在一篇关于科技发展对社会影响的文章后,有这样一道题:“作者认为科技发展带来的最大挑战是什么?”答案可能需要从文章中总结得出,如“作者认为科技发展带来的最大挑战是可能导致部分人失业以及引发信息安全问题”。
词汇理解题则需要我们准确掌握单词的词义、词性和用法。
比如,给出一个单词“phenomenon”,让我们选择它在句子中的正确释义。
我们需要知道这个单词常见的意思是“现象”,然后结合句子的语境来判断。
写作部分的课后习题主要是培养学生的书面表达能力和逻辑思维。
可能会要求写一篇议论文、记叙文或者说明文。
以议论文为例,题目可能是“是否应该在大学期间兼职”。
在写作时,首先要提出自己的观点,然后给出理由进行论证。
比如,如果认为应该兼职,可以提到兼职能够增加社会经验、锻炼人际交往能力、减轻家庭经济负担等。
