基于多元逐步回归的脑卒中发病影响因子分析

Analysis of stroke incidence impact factors based on stepwise multiple regression

对脑卒中发病影响因子进行了分析和研究。首先对庞大的病例信息进行了统计分析,然后通过回归拟合的方法建立了数学模型,确立了脑卒中发病率与气温、气压和湿度间的关系,最后就高危人群提出了一些建议。由此,对2012"高教社杯"全国大学生数学建模竞赛C题的各问题给出了完整的解答。

In this information through paper, stroke incidence impact factors were analyzed. First, the huge cases statistics and analysis, then it presented a mathematical model through regression fitting method, and established the relationship between stroke incidence and air temperature, barometric pressure and humidity. Last, it made some suggestions on the high-risk groups. As a result, the 2012 Higher Education Press Cup National Mathematical Contest in Modeling C title problem given a complete answer.
