例如:
a | s | c | d | e | f | g |
1 | 5 | 3 | 5 | 6 | 3 | 9 |
2 | 8 | 2 | 8 | 5 | 4 | 10 |
3 | 7 | 1 | 7 | 4 | 5 | 11 |
4 | 6 | 0 | 6 | 3 | 6 | 12 |
5 | 5 | -1 | 5 | 6 | 7 | 13 |
6 | 4 | -2 | 4 | 7 | 8 | 5 |
7 | 3 | -3 | 3 | 8 | 5 | 8 |
8 | 2 | 5 | 2 | 5 | 6 | 7 |
9 | 1 | 8 | 3 | 8 | 4 | 6 |
10 | 0 | 7 | 4 | 7 | 5 | 8 |
11 | -1 | 6 | 5 | 6 | 6 | 7 |
12 | -2 | 5 | 6 | 11 | 5 | 6 |
13 | -3 | 4 | 3 | 12 | 6 | 4 |
假设a与c ,c与e,a与f存在协整关系,想实现的结果是输出 a c,c e,a f。
