Section 3.1 introduces the formal definitions of random variable and its distribution, illustrated by several examples. The main properties of distribution functions, including a characterisation theorem for them, are presented in Sect. 3.2 . This is followed by listing and briefly discussing the key ...
Invertible functionsIn the case in which the function is neither strictly increasing nor strictly decreasing, the formulae given in the previous sections for discrete and continuous random variables are still applicable, provided is one-to-one and hence invertible. We report these formulae below. ...

Distribution Function: take the limit of other variables to +\infty F_{1}(x)=\lim _{y \rightarrow \infty} F(x, y), \quad F_{2}(y)=\lim _{x \rightarrow \infty} F(x, y) \\ For multivariate random vectors, \begin{aligned} F_{1}\left(x_{1}\right) &=\lim _{\substa...
5.3.2 Random Variables and Distribution Functions In this subsection, we discuss random variables and probabilistic distributions that are essential to reliability analysis. Random Variables A random variable is one whose value is determined by the outcome of a random experiment. In this chapter, X ...
个人觉得“连续随机变量函数的分布”这个表述有点绕,远不如英语的“Distribution of Functions of Random Variables”,所以加了个英文的标题 几个定理的证明的练习和笔记 先总结下思路脉络: 当g(x)为严格单调时 定理2.6.1是重点,后面的定理2.6.2~定理2.6.4都是基于定理2.6.1推导 ...
1. Continuous Random Variables and Probability Density Functions A random variable whose set of possible values is an entire interval of numbers is not discrete. Continuous Random Variables A random variable X is said to be continuous if its set of possible values is an entire interval of numbers...
3.7 Distributions and induced distribution functions 3.7节我们介绍分布以及分布函数,注意到之前我们讨论的内容是不涉及概率测度的,那么这一节我们会引入概率测度,导出随机变量的分布函数。 3.7.1 Case I: Random variables 首先来看一维情况 我们知道P是可测空间\left( \Omega,\mathcal{A}\right)其上的一个概率测...
