The chapter also discusses the distribution functions. If X is a random variable; the probability P ( X ≤ x ) is a function of the real variable x , then F X ( x ) = P ( X ≤ x) and call F X ( x ) the distribution function of the random variable X .EUGENE LUKACS...
2. 随机变量(Random Variable):数学定义上,其是从样本空间到实数的映射,使得每个实验结果对应一个数值。例如,掷骰子的结果可用随机变量表示为实数1-6。3. 概率分布(Probability Distribution):描述随机变量所有可能取值及其对应的概率。例如,公平骰子的概率分布中,每个数值的概率是1/6。分布可以是离散型(如二项分布)...

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 un...
A random variable X is said to be continuous if its set of possible values is an entire interval of numbers -- that is, if for some A<B, any number x between A and B is possible. Probability Distribution of Continuous Variables

3.3.2 How to check a random variable? 如何检验随机变量呢?其实就是在检验可测函数。定理3.3.1告诉我们检验的方法。不需要使用随机变量的原始定义:检验对所有的Borel集B都有X^{-1}(B),满足X^{-1}(B)\in\mathcal{A}。只需要检验X^{-1}([-\infty,x])\in\mathcal{A} ,\forall x\in\mathcal{...
本章主要介绍随机变量,离散型随机变量(discrete random variables),期望(expected value),方差(variance),Bernoulli试验和二项分布(The Bernoulli and Binomial random variables),Poisson分布(The Poisson Random Variable),累积分布函数(Cumulate Distribute Variance Function) 后面重要名词均以英语展示 Random Variable 定义...

Note the distinction between a random variable (which refers to the random process involved) and an observation (which is a fixed number, once it has been observed). The pattern of probabilities for a random variable is called its probability distribution. Many random variables have a mean and...
