多元P范分布密度函数的统一
The Unification of P-norm Distribution Density Functions
【摘要】 孙海燕、周世健等对P范分布及其参数估计理论作出了重大贡献,但他们提出了两种不同形式的P范分布密度函数.针对延续了10年的P范分布密度函数的形式差异和争议,讨论了两种不同形式的多元P范分布密度函数及其数据处理的特点,证明了两种不同形式的多元P范分布密度函数等价,从而统一了多元P范分布的理论基础,并提出有关的符号建议,以便于多元P范分布理论在数据处理中的推广应用.
【Abstract】 Sun Hai-yan & Zhou Shi-jian put forward two different kinds of p-norm distribution density functions after making important contributions to their assessment theory.This paper discusses the formal difference of p-norm distribution density functions on multi-variables,puts forward the equivalent proof of 2 different forms of p-norm distribution density functions with multi-variables and unifies the theoretic foundation of p-norm distribution functions.It also offers some suggestion on the notations for convenient popularization and application.
【Key words】 mathematics; p-norm distribution; density function; equivalence; notation;
