高手们，我在做面板数据模型的协整检验时，需要对多个经济变量进行协整检验。但是在用johansen检验时，提示变量太多。用kao检验时，结果如下：   
   t-Statistic Prob.
ADF   -5.946522  0.0000
   
Residual variance    0.002033
HAC variance    0.000558
   
   
   
Augmented Dickey-Fuller Test Equation   
Dependent Variable: D(RESID?)   
Method: Panel Least Squares   
Date: 01/18/11   Time: 11:07   
Sample (adjusted): 1999 2008   
Included observations: 10 after adjustments   
Cross-sections included: 11   
Total pool (balanced) observations: 110   
   
Variable Coefficient Std. Error t-Statistic Prob.  
   
RESID?(-1) -0.978954 0.125123 -7.823912 0.0000
D(RESID?(-1)) 0.046412 0.092659 0.500891 0.6175
   
R-squared 0.490069     Mean dependent var  -0.000423
Adjusted R-squared 0.485347     S.D. dependent var  0.047270
S.E. of regression 0.033911     Akaike info criterion  -3.912140
Sum squared resid 0.124195     Schwarz criterion  -3.863041
Log likelihood 217.1677     Hannan-Quinn criter.  -3.892225
Durbin-Watson stat 1.918814   
   
看不太懂，是不是只看ADF那一项拒绝原假设就可以？请指点！谢谢
