我利用Johansen协整检验得出结果为:
Unrestricted Cointegration Rank Test (Trace)
Hypothesized Trace 0.05
No. of CE(s) Eigenvalue Statistic Critical Value Prob.**
None * 0.063662 82.35834 69.81889 0.0036
At most 1 0.040290 41.18088 47.85613 0.1830
At most 2 0.013724 15.43741 29.79707 0.7511
At most 3 0.007366 6.786949 15.49471 0.6025
At most 4 0.003443 2.158811 3.841466 0.1418
Trace test indicates 1 cointegrating eqn(s) at the 0.05 level
* denotes rejection of the hypothesis at the 0.05 level
**MacKinnon-Haug-Michelis (1999) p-values
Unrestricted Cointegration Rank Test (Maximum Eigenvalue)
Hypothesized Max-Eigen 0.05
No. of CE(s) Eigenvalue Statistic Critical Value Prob.**
None * 0.063662 41.17746 33.87687 0.0057
At most 1 0.040290 25.74347 27.58434 0.0844

At most 4 0.003443 2.158811 3.841466 0.1418
Max-eigenvalue test indicates 1 cointegrating eqn(s) at the 0.05 level
应当为至多有一协整关系存在,且结果为:
1 Cointegrating Equation(s): Log likelihood -8239.074
