Probability Distributions for Discrete Random Variables(随机变量上的概率分布) probability mass function (pmf,概率质量函数) 这是我们高中时期最常见的分布情况,也就是每一个取值给一个概率 我们经常用条形统计图来表示 下面给出一个例子 如果说pmf的概率公式给定如下 那么我们有 联想到泰勒展开 然后根据这个可以算...

Random Variables (Single Variable)DefinitionA random variable is some function that assigns a real number X(s) to each possible outcome s \in S, where S is the sample space for an experiment.Random …
Probability inequalities of random variables, especially those of sums of random variables, play important roles in analytic probability theory, say, limiting theorems. Not only the applications of these inequalities, the proofs of these inequalities are also good illustrations of some important ...
Random variables produce probability distributions based on experimentation, observation, or some other data-generating process. Random variables allow us to understand the world around us based on a sample of data in this way. We know the likelihood that a specific value will occur in the real ...
ProbabilityWe can show the probability of any one value using this style:P(X = value) = probability of that valueExample (continued): Throw a die once X = {1, 2, 3, 4, 5, 6} In this case they are all equally likely, so the probability of any one is 1/6 P(X = 1) = 1/...

When we know the probability p of every value x we can calculate the Expected Value (Mean) of X:μ = ΣxpNote: Σ is Sigma Notation, and means to sum up.To calculate the Expected Value:multiply each value by its probability sum them up...
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...
