**scipy.stats.hmean(array, axis=0, dtype=None)**计算数组元素沿数组指定轴的调和平均值(python 中的列表)。
是公式–
![]()
参数:
数组:输入有计算调和平均值元素的数组或对象。
轴:计算平均值的轴。默认轴= 0
数据类型:可选。它设置返回元素的类型。
根据设定的参数返回:数组元素的调和平均值。
代码#1:
# Harmonic Mean
from scipy.stats.mstats import hmean
arr1 = hmean([1, 3, 27])
print("Harmonic Mean is :", arr1)
Output:
Harmonic Mean is : 2.18918918919
代码#2: 多维数据
# Harmonic Mean
from scipy.stats.mstats import hmean
arr1 = [[1, 3, 27],
[3, 4, 6],
[7, 6, 3],
[3, 6, 8]]
print("\nHarmonic Mean is :", hmean(arr1))
# using axis = 0
print("\nHarmonic Mean is with default axis = 0 : \n",
hmean(arr1, axis = 0))
# using axis = 1
print("\nHarmonic Mean is with default axis = 1 : \n",
hmean(arr1, axis = 1))
Output:
Harmonic Mean is : [ 2.21052632 4.36363636 6.04195804]
Harmonic Mean is with default axis = 0 :
[ 2.21052632 4.36363636 6.04195804]
Harmonic Mean is with default axis = 1 :
[ 2.18918919 4\. 4.66666667 4.8 ]
