摘要:

设X1,X2,…,Xn为一列非负独立同分布的随机变量,其分布为:Fα(x)=(1-α)F1(x)+αF2(x),其中α∈[0,1],F1(x),F2(x)都是定义在R+上的分布函数,现Y1,Y2,…,Yn为非负i.i.d～G(t)的截断随机变量列,并且Xi与Yi也相互独立,在仅能观察到:Zi=min(Xi,Yi),δi=I(Xi≤Yi)(i=1,2,…,n)的情况下,给出了污染系数α的估计,并在G(t)已知的情况下证明了其相合性.

Abstract:

Let X1,X2,...,Xn be a list of non-negative independent random variables with the same distribution, and its distribution is: Fα(x)=(1-α)F1(x)+αF2(x), where α∈[0,1], F1(x),F2(x) are all distribution functions defined on R+, now Y1, Y2,..., Yn are non-negative i.i.d~G(t) truncated random variable columns, and Xi and Yi are also independent of each other, and it can only be observed that Zi=min(Xi,Yi),δi=I( In the case of Xi≤Yi)(i=1,2,...,n), an estimate of the pollution coefficient α is given, and its compatibility is proved when G(t) is known.
