NettetI know the general formula for the CDF of order statistics. It is given by. F i ( t) = ∑ k = i n ( n k) F ( t) k ( 1 − F ( t)) n − k. Now, the CDF of a random variable is a measurable function. Thus F ( X ( i)) and F i ( X ( i)) are real valued random variables again. And a) asks for their distribution. Per definition, we have.
