sciPy stats.percentileofscore() | Python

scipy.stats.percentileofscore(a, score, kind='rank')函数帮助我们计算分数相对于分数列表的百分位排名。
假设 x 的百分位数是 60%，这意味着 a 中 80% 的分数低于 x。

Parameters : 
arr : [array_like] input array. 
score : [int or float] Score compared to the elements in array. 
kind : [optional] ‘rank’, ‘weak’, ‘strict’, ‘mean’. 
Results : Percentile of the scores relative to the array element. 

代码#1：

Python3

# percentileofscore
from scipy import stats
import numpy as np
 
# 1D array 
arr = [20, 2, 7, 1, 7, 7, 34]
print("arr : ", arr) 
 
print ("\nPercentile of 7  : ", stats.percentileofscore(arr, 7))
 
print ("\nPercentile of 34 : ", stats.percentileofscore(arr, 34))
 
print ("\nPercentile of 2  : ", stats.percentileofscore(arr, 2))

输出：

arr :  [20, 2, 7, 1, 7, 7, 34]

Percetile of 7  :  57.1428571429

Percetile of 34 :  100.0

Percetile of 2  :  28.5714285714
