[商管] [統計]-政大風管一題
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)
是要把他拆成F(Y10)-F(Y5)和F(Y2)-F(Y1)嗎
有位大大回答的部分是這樣
= Beta(5,6) + Beta(1,10)
5 1 11
= (ΣExp + ΣExp) / ΣExp
6 11
= ΣExp / ΣExp = Beta(6,5)
可以請問這是什麼意思嗎??
