摘要
以2001年至2013年的宿州市人口数据资料为依据,运用灰色系统理论建立GM(1,1)宿州市人口预测模型,并对该GM(1,1)预测模型进行残差检验,关联度检验和后验差检验,通过检验知模型对数据的拟合属于一级精度,模型精度较高。最后利用GM(1,1)模型对宿州市2014年至2018年的人口进行了预测,并结合宿州市人口发展的历史和现状对结果进行了分析。
This paper introduced the advantage and the application condition of GM ( 1, 1 ) model. Based on the data of Suzhou population from 2001 to 2013, this paper set up the GM( 1,1 ) model by applying the grey system, and made the residual examination, correlation degree test and posterior - variance test for the GM ( 1, 1 ) model. The tests showed that the accuracy of the model was high. At last, the paper used GM ( 1,1 ) model to forecast the population of Suzhou city from 2014 to 2018, and analyed the result with the population development history and present situation in Suzhou.
