scipy.stats.gilbrat() 是一个 gilbrat 连续随机变量，用标准格式和一些形状参数定义，以完成其规范。
参数: - > q : 上下尾概率 - > x : 分位数 - > loc : 【可选】位置参数。默认= 0 - >刻度:【可选】刻度参数。默认值= 1 - >大小:【整数元组，可选】形状或随机变量。 - >瞬间:【可选】由字母['mvsk']组成；m’=均值，‘v’=方差，‘s’= Fisher 偏斜度，‘k’= Fisher 峰度。(默认值= 'mv ')。
结果:吉尔布雷特连续随机变量
代码#1:创建吉尔布雷特连续随机变量
from scipy.stats import gilbrat
numargs = gilbrat .numargs
[] = [0.7, ] * numargs
rv = gilbrat ()
print ("RV : \n", rv)
输出:
RV :
<scipy.stats._distn_infrastructure.rv_frozen object at 0x000001E39A3B4AC8>
代码#2:吉尔布雷特随机变量和概率分布
import numpy as np
import numpy as np
quantile = np.arange (0.01, 1, 0.1)
# Random Variates
R = gilbrat.rvs(scale = 2, size = 10)
print ("Random Variates : \n", R)
# PDF
R = gilbrat.pdf(quantile, loc = 0, scale = 1)
print ("\nProbability Distribution : \n", R)
输出:
