关于随机向量的函数的同分布性

On Identically Distributed Property for Functions of a Random Vector

给出了一个随机向量的某些函数同分布的充分条件；对任意ｎ≥２，还提供了虽然ξｉ，１≤ｉ≤ｎ，同分布。但，不同分布的例子。

Some sufficient conditionS of identical distribution for some functions of a random vectorare given. Some examples showing that for arbitrary n≥2,although i,1≤i≤n,are identicallydlstributed,are not so,are also presented.
