是这样的,同样的程序同事和我跑出来的结果不一样,有细微的差别。
108个结果数据集中有6个不完全相同,具体如下。
| Name  | Records no of different | Variable of different | 
| 1_201108 | 5 out of 7656564 | Pre_u | 
| 2_201108 | 11 out of 14453130 | Pre_u | 
| C_201107 | 25 out of 240318 | Proj_p , the difference  usually  like this: 3.638E-11 | 
| C_201108 | 38 out of 240685 | Same as above | 
| B_201107 | 132 out of 51837 | Same as above | 
| B_201108 | 207 out of 52239 | Same as above | 
请问大家有这样的经验吗?这是为什么?
