单峰分布应用实例的演算
首发时间:2008-06-04
摘要:本文以社会经济的统计对象:居民收入统计资料的实例,以说明呈现的频数服从单峰分布。应用单峰分布密度函数的数学模型来描述其分布曲线,能够达到拟合的优度,从而提高统计推断的精确性。通过演算其分布任意区间的概率来验证单峰分布在实践中的意义。

Unimodal distribution application example calculation
Abstract:This article by social economy statistical object: The resident income statistics material's example, showed presents frequency obedience unimodal distribution. Applies the unimodal distribution density function the mathematical model to describe its distribution curve, can achieve the fitting the goodness of fit, thus enhancement statistical inference accuracy. Through calculates its distribution random sector probability to confirm unimodal distribution significance in reality.
