基于Weibull分布的脑卒中气象因素评估模型

Stroke Meteorological Factors Assessment and Early Warning Model based on the Weibull Distribution

采用统计学的方法,以某市脑卒中发病病例信息和当地四年的气象资料为依据,通过主成分分析方法,得出气象综合评估函数。利用Weibull分布的概率密度函数,建立脑卒中发病率与气象评估值的非线性回归模型,该模型经验证具有较好的拟合性。

Based on a city of stroke onset cases information and local four years of meteorological data, with princi- pal component analysis, the meteorological evaluation function is derived with the method of statistics. The inci- dence of stroke and meteorological assessment of the value of the non - linear regression model is established by u- sing Weibull distribution of the probability density function. It is proven to have a good fit.
