我用“全国的CPI”对“北京的CPI”进行一元回归时,得到如下结果,我刚入门,大家帮我解读下吧。
Dependent Variable: BEIJING
Method: Least Squares
Date: 01/23/08 Time: 22:12
Sample: 2001M01 2007M10
Included observations: 82
Variable Coefficient Std. Error t-Statistic Prob.
C 0.002868 0.002632 1.089470 0.2792
NATIONAL 0.385223 0.102918 3.743005 0.0003
R-squared 0.149027 Mean dependent var 0.009402
Adjusted R-squared 0.138390 S.D. dependent var 0.019218
S.E. of regression 0.017839 Akaike info criterion -5.190808
Sum squared resid 0.025457 Schwarz criterion -5.132108
Log likelihood 214.8231 F-statistic 14.01008
Durbin-Watson stat 0.647363 Prob(F-statistic) 0.000341
感觉参数C没通过显著性检检,不知道是不是?有什么方法可以补救的!
