摘要
针对非参数贝叶斯中的右中立过程先验的支撑问题展开了讨论,给出了右中立过程在两种特殊情形下的支撑:当它对应的Levy表示中没有非随机部分时,它以概率1离散;当它对应的Levy测度的支撑为(0,∞)×[0,1]时,支撑是(0,∞)上所有分布函数构成的集合.
he problem concerning the support of neutral to the right processes is discussed,and two supports in two particular cases are given.In case that the non-random part of the corresponding Levy representation doesn t exist,it shows a discrete distribution around probability one;while in case that the support of the corresponding Levy measure is all of(0,∞)× then its support will be the set of all distribution functions on(0,∞).
