(1)①首先分析人均寿命与人均GDP的数量关系,用Eviews分析:DependentVariable:YMethod:LeastSquaresDate:12/27/14Time:21:00Sample:122Includedobservations:-StatisticProb.  -    -            -    Hannan--    Durbin-(F-statistic),关系式为y=+②关于人均寿命与***识字率的关系,用Eviews分析如下:DependentVariable:YMethod:LeastSquaresDate:11/26/14Time:21:10Sample:122Includedobservations:-StatisticProb.  -    -            -    Hannan--    Durbin-(F-statistic),关系式为y=+③关于人均寿命与一岁儿童疫苗接种率的关系,用Eviews分析如下:DependentVariable:YMethod:LeastSquaresDate:11/26/14Time:21:14Sample:122Includedobservations:-StatisticProb.  -    -            -    Hannan--    Durbin-(F-statistic),关系式为y=+(2)①关于人均寿命与人均GDP模型,由上可知,,说明所建模型整体上对样本数据拟合较好。对于回归系数的t检验: 取α=,查t分布表得自由度为n-2=22-2=20的临界值(红色是自己加上的),t(β1)=>(20)=,对斜率系数的显著性检验表明,人均GDP对人均寿命有显著影响。②关于人均寿命与***识字率模型,由上可知,可决系数为
