※ 引述《windsinsky29 ()》之铭言：
: 这题以前好像有在板上看过
: 但是我不会的那部份没有解答
: 恳请高手帮忙 谢谢
: 题目如下
: Let Y1 < Y2 < .... < Y10 be the order statistics of a random
: sample of size 10 from a distribution of the continuous type
: having distribution function F(x).
: Determine the distribution of V = F(Y10) - F(Y5) + F(Y2) -F(Y1)
: 谢谢大家的帮忙
V = F(Y10) - F(Y5) + F(Y2) - F(Y1)
= Beta(5,6) + Beta(1,10)
5 1 11
= (ΣExp + ΣExp) / ΣExp
6 11
= ΣExp / ΣExp = Beta(6,5)
