你不是已经把过程说的很清楚了吗?除了格兰杰两步法,还可以首先选中两个序列,然后右键open as group,在G ...
cointegration test的结果怎么看
Series: DELX DELY
Sample (adjusted): 2 45
Included observations: 44 after adjustments
Null hypothesis: Series are not cointegrated
Automatic lags specification based on Schwarz criterion (maxlag=9)
Dependent tau-statistic Prob.* z-statistic Prob.*
DELX -6.881116 0.0000 -45.61480 0.0000
DELY -4.066797 0.0021 -24.08540 0.0023
*MacKinnon (1996) p-values.
Intermediate Results:
DELX DELY
