按你检验结果看,两个都是平稳的!每个变量都要检查,而且最好用多种方法进行检验,以提高稳健性!
(⊙o⊙)哦 非常感谢 我想再问一下 ADF检验看的是第一个P值吗?还是四个都要看啊
Fisher-type unit-root test for mbr
Based on augmented Dickey-Fuller tests
--------------------------------------
Ho: All panels contain unit roots Number of panels = 50
Ha: At least one panel is stationary Number of periods = 5
AR parameter: Panel-specific Asymptotics: T -> Infinity
Panel means: Included
Time trend: Not included
Drift term: Not included ADF regressions: 0 lags
------------------------------------------------------------------------------
Statistic p-value
------------------------------------------------------------------------------
Inverse chi-squared(100) P 207.4243 0.0000
Inverse normal Z -0.3950 0.3464
Inverse logit t(244) L* -3.6285 0.0002
Modified inv. chi-squared Pm 7.5960 0.0000
------------------------------------------------------------------------------
P statistic requires number of panels to be finite.
Other statistics are suitable for finite or infinite number of panels.
