论文摘要
令$（x_1，\ ldots，x_n）$为具有分布功能$ f $的可交换随机向量，并用$ y_1 \ leq \ cdots \ cdots \ leq y_n $表示相应的订单统计信息。我们表明，给定$（x_1，\ ldots，x_n）$的条件分布给定$（y_1，\ ldots，y_n）$不依赖$ f $。
Let $(X_1,\ldots,X_n)$ be an exchangeable random vector with distribution function $F$, and denote by $Y_1\leq \cdots\leq Y_n$ the corresponding order statistics. We show that the conditional distribution of $(X_1,\ldots,X_n)$ given $(Y_1,\ldots,Y_n)$ does not depend on $F$.
