For PM2.5 predictions,we use the correlation coefficient,principal component analysis,Newton in-terpolation and other methods,and then use SPSS,EVIEWS software.We test them by using residual analysis and K-S test to obtain a more satisfactory result.Finally,we put forward a proposal for local government in line with the results.%针对PM2.5的预测,使用相关系数,主成分分析,牛顿插值法等方法,利用SPSS,EVIEWS 等软件,建立PM 2.5预测的多元线性预测模型,并对模型的结果进行残差分析以及K-S检验,得到了较为理想的结果,最后,结合所得结果为当地政府提出了建议。
