脑卒中发病环境因素分析及干预的数学模型

The mathematical model for analysis and intervention of stroke onset’s environmental factors

依据2012年全国大学生数学建模竞赛C题所给的脑卒中发病病例信息,运用Excel软件筛选功能,将数据进行分类整理及统计规律分析,发现脑卒中发病人群易集中于老年人,男性得病比例高于女性,春季为此病发作高峰期,农民患此病人数最多.在合理假设的基础上,运用MATLAB软件进行多元线性回归分析,建立了脑卒中发病与环境因素关系的数学模型.通过数学模型及脑卒中高危人群的重要特征和关键指标,指出脑卒中发病的规律,对脑卒中高危人群进行预警和干预.

According to the Problem C in the stroke onsets stipulated in Chinese Undergraduate Mathematical Contest in Modeling （2012）, Excel software-filtering is used for data sorting and statistical analyses of the stroke onset, gender, age, occupation and season. Result shows that the aged are prune to the stroke, the male being more than the female, spring being the peak. Based on the MATLAB for the multiple linear regression analysis, a mathematical model is created describing the stroke onset related to the environmental factors.
