1、（财务知识）计量经济学作业20XX年XX月多年的企业咨询豉问经验.经过实战验证可以落地机行的卓越管理方案，值得您下载拥有计量经济学系别：国贸系班级：08商行壹班姓名：王善勇学号：2008018149壹、数据变换createa19852003dataCrCuYrYuRpopPopPPrPu人均消费genrC1=(Cr*Rpop/100+Cu*(1-Rpop/100)/P*100人均可支配收入genrY1=(Yr*Rpop/100+Yu*(1-Rpop/100)/P*100农村人均消费：genrCr1=Cr/Pr*100城镇人均消费：genrCu1=Cu/Pu*100农村人均纯收入：genrYr1

2、=Yr/Pr*100城镇人均可支配收入：genrYu1=Yu/Pu*100二、图形分析全国消费情况分析：scatY1C1从图形中见出Y1和C1大致线形关系，即人均可支配收入和人均消费大致呈线形关系。农村消费情况分析：scatYr1Cr1从图中能够见出YR1和CR1大致符合线形关系，所以农村人均纯收入和农村人均消费大致呈线形关系城镇消费情况分析：scatYu1Cu1从图中能够见出YU1和CU1大致呈线形关系，即城镇人均可支配收入和城镇人均消费大致呈线形关系。三、估计线性回归模型全国消费情况分析：IsCICylDependentVariable:C1Method:LeastSquaresDate:
