第二章简单线性回归模型

(1) ①首先分析人均寿命与人均 GDP的数量关系,用 Eviews 分析:
Dependent Variable: Y
Method: Least Squares
Date: 12/27/14 Time: 21:00
Sample: 1 22
Included observations: 22
Variable Coefficient Std. Error t-Statistic Prob.
C
X1
R-squared Mean dependent var
Adjusted R-squared . dependent var
. of regression Akaike info criterion
Sum squared resid Schwarz criterion
Log likelihood - Hannan-Quinn criter.
F-statistic Durbin-Watson stat
Prob(F-statistic)
有上可知,关系式为 y=+ 1
②关于人均寿命与***识字率的关系,用 Eviews 分析如下:
Dependent Variable: Y
Method: Least Squares
Date: 11/26/14 Time: 21:10
Sample: 1 22
Included observations: 22
Variable Coefficient Std. Error t-Statistic Prob.
C
X2
R-squared Mean dependent var
Adjusted R-squared . dependent var
. of regression Akaike info criterion
Sum squared resid Schwarz criterion
Log likelihood - Hannan-Quinn criter.
F-statistic Durbin-Watson stat
Prob(F-statistic)
由上可知,关系式为 y=+ 2
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:
Dependent Variable: Y
Method: Least Squares
Date: 11/26/14 Time: 21:14
Sample: 1 22
Included observations: 22
Variable Coefficient Std. Error t-Statistic Prob.
C
X3
R-squared Mean dependent var
Adjusted R-squared . dependent var
. of regression Akaike info criterion
