摘要
对于离散型随机变量X来说,为了得到它的似然估计,就必须求得概率函数.该文对取得有限个值的离散型随机变量,给出了概率函数的两种表达形式.
In order to obtain the likelihood function of a descrete stochastic variable, it is necessary to work out its probability function first. In this paper, two kinds of representation about probability function as a descrete stochastic variable with finite values are given.
