作为这个问题的后续,我将多元Logistic回归与定量和定性解释变量之间的相互作用进行了拟合.MWE如下:

Type  <- rep(x=LETTERS[1:3], each=5)
Conc  <- rep(x=seq(from=0, to=40, by=10), times=3)
Total <- 50
Kill  <- c(10, 30, 40, 45, 38, 5, 25, 35, 40, 32, 0, 32, 38, 47, 40)

df <- data.frame(Type, Conc, Total, Kill)

fm1 <- 
  glm(
      formula = Kill/Total~Type*Conc
    , family  = binomial(link="logit")
    , data    = df
    , weights = Total
    )

summary(fm1)

Call:
glm(formula = Kill/Total ~ Type * Conc, family = binomial(link = "logit"), 
    data = df, weights = Total)
