偏最小二乘回归方法在地理与经济的相关性分析中的应用研究

Study on Application of PLS in Correlation Analysis between Geographical Parameters and Economical Development Parameters

在建立地理因子库和经济因子库的基础上 ,利用偏最小二乘回归方法对地理因子与经济因子进行了回归建模 ,并把得到的回归系数用来解释两类因子之间的相关关系 ,达到了对地理要素和国民经济指标之间的相关关系定量化研究之目的。

In this paper, the correlation analysis between geographical parameters and economical development parameters based on the databases of geographical parameters and economical development parameters is investigated with PLS. The theoretical and experimental results indicate that PLS regression methods are quite feasible and effective, and they can meet the needs of quantitative analysis of geographical parameters and economical parameters.
