如果我有这样一个数据集:
Object1 Object2 Outcome1 Outcome2 Total_TestsObject1 Total_TestsObject2 TotalOutcomes_Object1 TotalOutcomesObject2
A C 0 1 0 0 0 0
D A 0 1 0 1 0 0
B E 1 0 0 0 0 0
F B 0 1 0 1 0 1
A B 1 0 2 2 1 2
A C 0 1 3 1 1 1
D A 0 1 1 4 0 1
B E 1 0 3 1 1 0
F B 0 1 1 4 0 2
A B 1 0 5 5 3 3
我要做的是创建两列:
列1跟踪Object1中的项,并将它以前的所有唯一对相加,如下所示。totaloutcouts\u ObjectX/Total\u TestsObjectX 由于Object1中的项以前可能在Object2中,求和必须在两个对象中找到唯一的对
我知道这一点还不清楚,但仍在努力找到一种正确表述的方法。但这里有一个例子
在最后一排我们有一个&;B类
A以前最接近事件的唯一对
A D row 7
A c row 6
B的前几对最接近该事件
B F row 9
B E row 8
在找到这些对之后,求和如下
Column 1(Object1): Sum: (D_Outcomes + C_outcomes) / (D_TotalTest + C_TotalTest)
= (1 + 1)/(1 + 1)=1
Column 2(Object2): Sum: (F_Outcomes + E_outcomes) / (F_TotalTest + E_TotalTest)
= (1 + 1)/(1 + 1)=1
所以这个过程遍历每一行,找到所有之前的唯一对,然后进行求和
我不知道用python怎么做
Input
{
Object1:[ A, A, B, C, A, F, B]
Object2:[C, D, E, D, B, E, D]
Outcome1:[1, 0, 1, 0, 0, 1, 0]
Outcome2:[0, 1, 0, 1, 1, 0, 1]
TotalOutcomes_Object1:[0, 0, 0, 1, 1, 0, 0]
TotalOutcomes_Object2:[0, 0, 0, 0, 0, 1, 0]
Total_TestsObject1:[0, 1, 0, 1, 2, 0, 2]
Total_TestsObject2:[0, 0, 0, 1, 1, 1, 2]
}
条件:
由于对象可以同时作为Object1和Object2,求和必须在Object1和Object2中找到对象的唯一外观;对象2
由于总的结果和总的测试都是在产生结果和进行测试时计算的,所以必须找到所有唯一的对象对,并返回它们的结果和最新的总的测试
Example:
Let's say A(Object1) and B(Object2) are a pair
A has previously been a pair with D, E and F
B has previously been a pair with C, D, G
Column1 then sums all of A's previous pair partners, meaning D, E, F
in the following way.
Sum: (D_Outcomes + E_outcomes + F_outcomes) / (C_TotalTest + D_TotalTest + F_outcomes)
Column2 then sums all of B's previous pair partners, meaning C,D, G
in the following way.
Sum: (C_Outcomes + D_outcomes + G_outcomes) / (C_TotalTest + D_TotalTest + G_outcomes)
The importance in this summations is that the pair partners latest stats are used, this is because both TotalOutcomes and TotalTest are counted up as they occur.
