如题,还有我做多元回归时t 检验没有通过。不知道有哪位高人能帮我看看。以下是我的回归结果:
Dependent Variable: LNGDG
Method: Least Squares
Date: 05/30/10 Time: 22:48
Sample: 1980 2006
Included observations: 22
Variable Coefficient Std. Error t-Statistic Prob.
LNK 0.309270 0.308738 1.001726 0.3298
LNL 0.142675 0.312506 0.456551 0.6535
LNR 1.085812 0.461001 2.355338 0.0301
C 1.249113 2.247694 0.555731 0.5852
R-squared 0.244786 Mean dependent var -3.128724
Adjusted R-squared 0.118917 S.D. dependent var 0.920510
S.E. of regression 0.864046 Akaike info criterion 2.708585
Sum squared resid 13.43836 Schwarz criterion 2.906956
Log likelihood -25.79443 F-statistic 1.944765
Durbin-Watson stat 1.509507 Prob(F-statistic) 0.158571
拟合度也不是很好。。。
