Description:

The damage carrots data set from Phelps (1982) was used by McCullagh and Nelder (1989) in order to illustrate diagnostic techniques because of the presence of an outlier. In a soil experiment trial with three blocks, eight levels of insecticide were applied and the carrots were tested for insect damage.

Variables:

A data frame with 24 observations on the following 5 variables.

success

integer giving the number of carrots with insect damage.

total

integer giving the total number of carrots per experimental unit.

logdose

a numeric vector giving log(dose) values (eight different levels only).

block

factor with levels B1 to B3
