摘要
设X服从以α和λ为参数的对数伽玛分布或负对数伽玛分布,V服从以β为参数的负幂分布,则在X<V条件下,证明了对数伽玛分布及负对数伽玛分布的条件概率的封闭性.
X reconciles ioggamma distribution or negative Ioggamma distribution for a and λ. V reconciles negative power distribution for β. On condition that X is less than V, we have proofed the conditional probability closeness about loggamma distribution and negative loggamma distribution.
