小弟用VAR模型来做股指和期指之间的关系问题。通过单位根检验发现两个变量不平稳,皆为一阶单整序列。因此做了差分变换,然后对原序列用Eviews进行了协整检验,检验结果如下
Date: 12/08/15 Time: 17:10
Sample (adjusted): 12 6000
Included observations: 5989 after adjustments
Trend assumption: Linear deterministic trend
Series: FUTURE STOCK
Lags interval (in first differences): 1 to 10
Unrestricted Cointegration Rank Test (Trace)
Hypothesized Trace 0.05
No. of CE(s) Eigenvalue Statistic Critical Value Prob.**
None 0.001726 14.96511 15.49471 0.0600
At most 1 * 0.000771 4.619737 3.841466 0.0316
Trace test indicates no cointegration 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 0.001726 10.34537 14.26460 0.1902
At most 1 * 0.000771 4.619737 3.841466 0.0316
Max-eigenvalue test indicates no cointegration at the 0.05 level
* denotes rejection of the hypothesis at the 0.05 level
**MacKinnon-Haug-Michelis (1999) p-values
Unrestricted Cointegrating Coefficients (normalized by b'*S11*b=I):

Unrestricted Adjustment Coefficients (alpha):

D(STOCK) -0.085712 -0.032053
1 Cointegrating Equation(s): Log likelihood -29931.42
Normalized cointegrating coefficients (standard error in parentheses)
FUTURE STOCK

Adjustment coefficients (standard error in parentheses)
D(FUTURE) -0.000285
(0.00172)
D(STOCK) 0.002788

想问一下怎么去看这个检验结果?是存在协整关系还是不存在?谢谢~~~
