| 摘 要： | 本文探讨了熵极大识别(EMI)准则的数学特性,分析了该准则与极大似然法的相互关系,并借助该准则导出了常见的各种概率密度函数,对不同分布之间的差异从不确定性的角度进行了理论分析,最后以P—Ⅲ型分布为例,讨论了参数识别的具体方法与步骤。

| Abstract: | The mathematic properties of the entropy maximum identification (EMI) criterior and the relationship between the EMI criterior and the method of maximum likelihood have been investigated in this paper.Many probability density functions have been derived and the reason for the difference among the probabilistic models analyzed.Then the author has discussed the procedure for identifying distribution parameter by the EMI criterior. |
