For an arbitrary non-decreasing function g, the inverse function g (−1)(x) is defined by the equation $$g^{(-1)}(y):=\inf\bigl\{x:g(x)\ge y\bigr\}=\sup\bigl\{x:g(x)<y\bigr\}. $$ 6. For a more detailed discussion of connections between causal and probabilistic ...
The distribution function of T is (16)F(t)=1−(1+(λt)γ)−n,t,n,λ>0,γ≥1. A random variable T with c.d.f. as given by Eqs. (15) and (16) are generalized log-logistic distribution with parameters (m, 1) and (1, n), respectively. We call Eq. (15) as ...

1)分布函数的弱收敛(Weak Convergence of the Distribution Function) 定义1 对于分布函数列{Fn(x)},如果存在一个非降函数F(x)使 在F(x)的每一连续点上都成立,则称Fn(x)弱收敛于F(x),并记为 。 中心极限定理就是一个分布函数弱收敛的例子。
二、随机变量(Random Variable)和概率分布函数(Probability Distribution Function) 1、随机变量(Random Variable) 如果A为某个随机事件,则一定可以通过如下示性函数使它与数值发生联系: 这样试验的结果就能有一个数 来表示,这个数是随着试验的结果的不同而变化,也即它是样本点的一个函数,这种量以后称为随机变量,随机...
The inverse distribution function (IDF) forcontinuous variablesFx-1(α) is the inverse of thecumulative distribution function(CDF). In other words, it’s simply the distribution function Fx(x) inverted. The CDF shows the probability a random variable X is found at a value equal to or less ...
