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...
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 cumulative distribution function (CDF) of random variableXXis defined as FX(x)=P(X≤x),for allx∈R.FX(x)=P(X≤x),for allx∈R. Note that the subscriptXXindicates that this is the CDF of the random variableXX. Also, note that the CDF is defined for allx∈Rx∈R. Let us lo...
Let H( y) denote the cumulative distribution function of (Y)]Then H(y)=P(G-1[F(Y)]≤y=P[F(Y)≤G(y)]=P(Y≤F-1[G(y)]=F(F-1[G(y)]=G(y)相关推荐 1Let y be a continuous random variable whose cumulative distribution function, F( y) , is strictly monotone Let G( y) ...
Many times, in practice, however, it is not simply the measured random variable that is of interest to us. Rather, it is some function of that random variable that is of primary concern. In this chapter, we discuss three distinct techniques, each of which is valuable in different ...
