常见的概率分布类型(一)(Probability Distribution I) 统计学中最常见的几种概率分布分别是正态分布(normal distribution),t分布(t distribution),F分布(F distribution)和卡方分布(χ2 distribution,chi-square distribution),其中后三种属于抽样分布。 为什么要研究概率分布呢?因为通过研究概率分布,我们可以找出数据的分...

位于区间(−∞,z)的x的概率由累积分布函数(cumulative distribution function) 给出。定义为: P(x)=∫−∞zp(x)dx(3) 概率密度的加和规则和乘积y规则的形式为 p(x)=∫p(x,y)dy(4)p(x,y)=p(x|y)p(y)(5) 加和规则的正确性可以⾮形式化地观察出来:把每个实数变量除以区间的宽度Δ,然后考虑...
例6.8 伯努利分布(Bernoulli distribution)是状态x∈{0,1}的单个二值随机变量X的分布。它受单个连续参数μ∈[0,1]控制,表示X=1的概率。伯努利分布Ber(μ)定义为 p(x∣μ)=μx(1−μ)1−x,x∈{0,1}E[x]=μV[x]=μ(1−μ) 其中E[x]和V[x]是二值分布随机变量X的均值和方差。 一个可以...
