Research on the Application of Gross National Product Based on Indexed Principal Component Analysis

Abstract

Before the principal component analysis of the raw data, the indexed method is used to preprocess the raw data. The factors influencing the GDP growth on provinces and cities are analyzed by the indexed principal component analysis method, and the data are simulated by Matlab software. Based on the output results of princomp function, the principal components reflecting the GDP growth are extracted to provide theoretical support for economic decision-making
