用Stata,想生成很多列数据t1,t2,t3……,实现
ge t1= cf if co==1,
ge t2= cf if co==2,
ge t3= cf if co==3,
ge t4= cf if co==4
……
ge t100= cf if co==100
co的值有很多(例如1-200),可以做成循环吗,怎么做?
求助各位,谢谢!
例子如下或者如附件
| id | cf | co | t2 | t3 | t4 |
| 1 | 9 | 2 | 9 | | |
| 2 | 0 | 2 | 0 | | |
| 3 | 0 | 3 | | 0 | |
| 4 | 0 | 4 | | | 0 |
| 5 | 7 | 4 | | | 7 |
| 6 | 2 | 4 | | | 2 |
| 7 | 3 | 4 | | | 3 |
| 8 | 6 | 5 | | | |
| 9 | 7 | 5 | | | |
| 10 | 9 | 5 | | | |
| 11 | 9 | 6 | | | |
| 12 | 12 | 6 | | | |
| 13 | 3 | 6 | | | |
| 14 | 16 | 7 | | | |
| 15 | 9 | 7 | | | |
| 16 | 9 | 8 | | | |
