空气质量数据校准问题的数学模型

The Mathematical Model of Air Quality Data Calibration

文章研究了2019年"高教社杯"全国大学生数学建模竞赛D题,该问题要求对空气质量的数据进行分析和校准。对数据进行预处理后,利用SPSS统计分析对国控点数据和自建点数据进行了探索性数据分析,运用Excel函数说明了国控点数据和自建点数据差异性的原因,基于多元线性回归建立了数据校准模型,并对模型进行了检验。

This paper studies problem D of the 2019“Higher Education Press Cup”national college students mathematical modeling contest,which requires analysis and calibration of air quality data.After preprocessing the data,this paper uses SPSS statistical analysis to conduct exploratory data analysis on the data of national control point and self-built point.The excel function is used to explain the reasons of the difference between the data of national control point and self-built point.Based on the multiple linear regression,a data calibration model is established and tested.
