一、使用MATPLOTLIB绘制PMF Matplotlib是Python中非常流行的绘图库,适合用于绘制各类图表,包括PMF。我们可以通过它简单地创建条形图,展示离散数据的概率分布。 1.1 准备数据 首先,我们需要准备一组离散数据。这些数据可以是实验结果、模拟数据或者从某个离散概率分布生成的数据。假设我们有一组骰子掷出的结果: import nump
ppf,比如 scipy.norm.ppf,是Python SciPy 中一种特殊的已知概率求临界值 a 的函数 1 cdf,Cumulative distribution function, 累积分布函数 用来计算概率 通过积分的方式,计算某个具体取值之前的函数 (pmf, 也叫pdf 函数) 面积,比如 p(x<=a) 的概率 Parini and Belanca, 2015 1.1 计算题举例 - 连续分布 :...
random.normal(0, 1, (M, K)) U = Y I = data2mat(train, N, M) # get the indicator function rmse=[] rms=RMSE(U,V,test,Level) rmse.append(rms) for ste in range(Step): for data in train: u=data[0] i=data[1] r=data[2] rui=(r-1)/(Level-1); Iu=I[u] Yu=Y[u]...
一. 概念解释 PDF:概率密度函数(probability density function), 在数学中,连续型随机变量的概率密度函数(在不至于混淆时可以简称为密度函数)是一个描述这个随机变量的输出值,在某个确定的取值点附近的可能性的函数。 PMF : 概率质量函数(probability mass function), 在概率论中,概率质量函数是离散随机变量在各特定...
