: 這題以前好像有在板上看過
: 但是我不會的那部份沒有解答
: 懇請高手幫忙 謝謝
: 題目如下
: 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)
: 謝謝大家的幫忙
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)
