摘要: |
讨论了4种二项分布的经验贝叶斯估计,并通过实例比较了这4种方法的优缺点.其中参数化方法缺点是要注意先验分布的选择;最小熵方法的缺点是只能采用数值解法;线性经验贝叶斯方法的优点是不需求出先验分布,结果简明,便于应用,缺点是需要估计局限于样本x的线性函数;条件期望法的优点是不必考虑先验分布的类型、参数等,只需要有充分多的“经验”样本. |

Abstract: |
In this paper,four kinds of empirical estimations on binomial distribution are discussed.The advantages and disadvantages of the estimations are contrasted by examples.If a,b>0,the parametric method takes active.But in practice a<0 or b<0,we must consider |
