基于均值化主成分分析的城镇居民消费性支出应用研究

Research on the Application of Urban Residents' Consumptive Expenditure Based on Equalization of Principal Component Analysis

均值化主成分分析是在传统主成分分析法的基础上,采用均值化方法对数据进行预处理的一种改进方法。利用均值化主成分分析法对全国各地区城镇居民的人均消费支出情况进行分析,并使用Matlab平台进行仿真,最终提取出反映消费支出的主成分,为下一步的研究工作提供必要的决策支持。

Equalization of principal component analysis based on the traditional principal component analysis method is an improved method using equalization of data preprocessing. In this paper, the per capita consumptive expenditure of urban residents in different regions of China is analyzed by equalization of principal component analysis method, and use Matlab to simulate. Finally the main components of consumptive expenditure are extracted and provide necessary decision support for future research.
