Bliss (1935) Beetle Mortality Data

Description

Mortality of adult flour beetle after five hours' exposure to gaseous carbon disulphide.

Usage

data("BeetleMortality")

Format

A data frame containing 8 observations on 3 variables.

dose

numeric. \log_{10} dose.

died

integer. Number killed.

n

integer. Number exposed.

Details

The data originates from Bliss (1935) and has been reanalyzed frequently.

Examples

## data
data("BeetleMortality", package = "glmx")

## various standard binary response models
m <- lapply(c("logit", "probit", "cloglog"), function(type)
  glm(cbind(died, n - died) ~ dose, data = BeetleMortality, family = binomial(link = type)))

## visualization
plot(I(died/n) ~ dose, data = BeetleMortality)
lines(fitted(m[[1]]) ~ dose, data = BeetleMortality, col = 2)
lines(fitted(m[[2]]) ~ dose, data = BeetleMortality, col = 3)
lines(fitted(m[[3]]) ~ dose, data = BeetleMortality, col = 4)
