R语言学习记录： logistic回归 如何计算OR值（3种方法）

以framingham数据为例，先建立模型

load("framingham.Rdata")

#哑变量

framingham$male<-factor(framingham$male,

levels = c(0,1),

labels = c("女性","男性"))

framingham$education<-factor(framingham$education,

levels = c(1,2,3,4),

labels = c("高中以下","高中","大学","大学以上"))

framingham$currentSmoker<-factor(framingham$currentSmoker,

levels = c(0,1),

labels = c("不吸烟","吸烟"))

framingham$BPMeds<-factor(framingham$BPMeds,

levels = c(0,1),

labels = c("不服用","服用"))

framingham$prevalentStroke<-factor(framingham$prevalentStroke,

levels = c(0,1),

labels = c("无脑卒中家族史","有脑卒中家族史"))

framingham$prevalentHyp<-factor(framingham$prevalentHyp,

levels = c(0,1),
