扩展线性支出系统模型估计方法的修正及实证检验

最小二乘估计扩展线性支出系统模型是利用横截面数据进行消费结构研究中经常使用的计量方法。从在估计过程中有时会遇到常数项不显著的问题,而目前尚无好的解决办法这一问题出发,对目前的估计方法进行了修正并作了实证检验。

Expanded Linear Expenditure System Model:Correction and Test with Examples

Least square regression Expanded Linear Expenditure System (ELES) model is the measuring method frequently used in consumption structure study done by means of sectional data.Sometimes there is the problem of insignificance of the constant in the process of estimation and there is not a proper approach to settling the problem at present.Based on this problem,the paper corrects the present estimation method and tests the new estimation test.
