针对戒烟天数的影响因素,综合使用相关分析、主成分分析、回归分析以及可靠性分析等方法,分别构建Pearson相关分析、曲线估计、主成分分析、多元线性回归和Alpha信度模型,使用MATLAB、SPSS、EVIEWS、EXCEL等软件,得出累计发病率的影响因素和戒烟天数的影响机理。
In view of the influence factors of smoking cessation days,using correlation analysis,principal component analysis,regression analysis and reliability analysis,Pearson correlation analysis,curve estimation,principal component analysis,multivariate linear regression and Alpha reliability model were constructed,and SPSS,EVIEWS,EXCEL and MATLAB were used to get the influence factors and the influence mechanism of the cumulative incidence.
