In courtiol/LM2GLMM: Data science for biologists: Generalized linear modelling with R

Poison data (taken from package fastR)

Description

The data give the survival times (in hours) in a 3 x 4 factorial experiment, the factors being (a) three poisons and (b) four treatments. Each combination of the two factors is used for four animals. The allocation to animals is completely randomized.

Usage

poison

Format

A data frame with 48 observations on the following 3 variables.

Poison

type of poison (1, 2, or 3)

Treatment

manner of treatment (1, 2, 3, or 4)

Time

time until death (hours)

Source

These data are also available from OzDASL, the Australian Data and Story Library (http://www.statsci.org/data/). (Note: The time measurements of the data at OzDASL are in units of tens of hours.)
