大Pandas的同位素当量

Question

我一直在绞尽脑汁试图将一个解决方案复制到熊猫的sql练习中。 本练习包含使用NTILE函数创建1个百分位箱，以计算某些指标

源数据集如下所示，我要除以的百分位数是度量值列：

source df

这就是我想要得到的（首先创建“Ntile”等价物，然后按它分组，用min max和count标记）

destination df

尝试使用qcut，但由于值相似而遇到错误

尝试的代码：

cuts = 100
weightdf = healthdf[healthdf["measure"] == "weight"].copy()
weightdf["Ntile"] = pd.qcut(weightdf["measure_value"].sort_values(), cuts , labels = range(1, 
cuts + 1))

这创建了一个“Bin edges must unique”错误，更改duplicates参数无效。 希望有人能帮忙，我相信有办法解决这个问题。 谢谢

编辑#2由于练习需要将值放入相等的零件箱中，因此我使用了在david发布的链接中找到的以下代码：

cuts = 100
weightdf = healthdf[healthdf["measure"] == "weight"].copy()
weightdf["Ntile"] = 
pd.qcut(weightdf["measure_value"].rank(method='first'), cuts, labels = 
range(1, cuts + 1))
weightdf.groupby("Ntile")["measure_value"].agg(["min","max","count"])

它现在的工作方式与sql中的工作方式完全相同

Answer 1

如果您发布的imgur实际上是您的数据帧，那么问题在于您正在单行数据帧上执行qcut。如何将一行分割成100个分位数？Pandas正在尝试创建一组具有不同分位数值的容器，但由于您只有一个观测值，因此所有这些容器都在同一个位置开始和结束。我可以通过使用单行df重新创建错误来证明这一点：

weightdf = pd.DataFrame(dict(weights=[10])) 
pd.qcut(weightdf["weights"].sort_values(), cuts )

返回

ValueError: Bin edges must be unique:

TLDR：如果要将df拆分为分位数，则需要在df中包含多行

Answer 2

（OP发布数据后的新答案。对于具有不同数据的相同错误消息，第一个答案仍然有效）

问题似乎在于数据集中存在多个重复的权重。要了解这是一个问题的原因，请参阅以下简单示例：[1,2,3,4,5,5,5,5,9,10]。让我们试着用十分位数来表示。当然，我们注意到第五、第六、第七和第八个十分位数是5。那么我们把5放在哪个箱子里呢？我们可以任意地将不同的五分成不同的十位数，如this answer所述，但是，这通常是误导性的（因此我有一个单独的答案）。我认为最合乎逻辑的做法是“四舍五入”，并说没有任何元素适合第五、第六或第七个十分位数，所有五个元素都适合第八个十分位数。为此，请使用以下代码（该代码用于原始数据的分位数，而不是示例数据的十分位数）：

edges = np.quantile(weightdf.measure_value,np.arange(0.01,1.01,0.01))                                                                                                                                                                    
unique_edges = np.unique(edges)                                                                                                                                                                                                           
labels = [ 1 + np.where(unique_edge == edges)[0][-1] for unique_edge in unique_edges ]                                                                                                                                                   
weightdf["Ntile"] = pd.cut(weightdf.measure_value, np.insert(unique_edges,0,0), labels=labels)
