摘要
For an order statistic (X(1:n). . .,X(n:n)) of a collection of independent but not necessarily identically distributed random variables, and any i is an element of {1,..., n}, the conditional distribution of (X(i+ 1:n), . . .,X(n:n)) given X(i:n) > s is shown to be stochastically increasing in s. This answers a question by Hu and Xie (2006).
