家庭收入分析

Analysis of Family Income

本文应用计量经济学的方法,建立家庭收入的数学模型和家庭收入的分布函数。分析影响家庭收入的主要因素,同时确立家庭收入与其主要影响因素之间的定量关系。然后,把家庭收入拟合于三参数的对数正态分布,并用迭代的方法求出分布的参数。

In this paper,with the methods of econometrics,we describe mathematical model and distribution function of family income.And we study the main factors influencing family income and determine quantitative relations between family income and the main factors.Then we fit family income distribution with three-parameter Iognormal distribution,and using iteration method,we determine three parameters of lognormal distribution.
