对面板数据序列包括三个解释变量序列和被解释变量序列,单位根检验结果是被解释变量序列是0阶平稳序列,即I(0),三个解释变量序列中两个是I(2),另一个是I(0),这样可以协整吗?利用上述变量进行协整检验,KAO检验通过,
Pedroni检验结果如下:
Alternative hypothesis: common AR coefs. (within-dimension) |
| | | | Weighted | |
| | Statistic | Prob. | Statistic | Prob. |
Panel v-Statistic | -2.830925 | 0.9977 | -3.569569 | 0.9998 |
Panel rho-Statistic | 4.727530 | 1.0000 | 4.162874 | 1.0000 |
Panel PP-Statistic | -5.912653 | 0.0000 | -10.48674 | 0.0000 |
Panel ADF-Statistic | -9.109818 | 0.0000 | -6.538607 | 0.0000 |
Alternative hypothesis: individual AR coefs. (between-dimension) |
| | | |
| | Statistic | Prob. |
Group rho-Statistic | 7.174103 | 1.0000 |
Group PP-Statistic | -14.06188 | 0.0000 |
Group ADF-Statistic | -11.63505 | 0.0000 |
请问这样能说变量之间存在协整关系吗?该如何做下去?
