随机变量的商逆及其分布

The reciprocal inverse of a random variable and its distribution

定义了随机变量的商逆分布,然后推导了常见一元分布的逆分布,进一步还推导了包括矩阵β分布在内的一些矩阵分布的逆分布。

After defining the reciprocal inverse of a random variable,this paper derive some inverse distribution of ordinary uni-distribution used in statistics.On the other hand,we obtain some inverse matrix distribution,such as matrix-β distribution and so on.
