我用Y1到Y5五个序列来解释Y,每个序列都是非平稳的，ADF判断回归方程的残差也是平稳的，为此想建立误差校正模型。通过Johansen 协整检验时其结论为

Unrestricted Cointegration Rank Test (Trace)                               
Hypothesized  Trace 0.05 
No. of CE(s) Eigenvalue Statistic Critical Value Prob.**
    
None *  0.841345  228.2222  95.75366  0.0000

At most 5  0.008899  0.384389  3.841466  0.5353

我的问题是：1 这种多变量，并且协整关系不是1的适不适合用误差校正模型EMC,还是应该用向量误差修正模型

                     2 本例中协整关系是5代表什么意思

请有兴趣的朋友帮忙看看
