弱弱地问下,我在做完异方差和自相关检验后,出来下面的结果,不太看得懂。。有没高手帮忙下,是不是存在自相关和异方差??谢谢。。
异方差检验结果:
Regression with Driscoll-Kraay standard errors Number of obs = 116
Method: Fixed-effects regression Number of groups = 29
Group variable (i): place F( 4, 28) = 1.08
maximum lag: 1 Prob > F = 0.3865
within R-squared = 0.2555
自相关检验结果:
Wooldridge test for autocorrelation in panel data
H0: no first order autocorrelation
F( 1, 28) = 0.985
Prob > F = 0.3296
