Usage

data(fabric)

Arguments

Format

A data frame with 32 observations on the following 3 variables.

leng

the length of the roll : a numeric vector

y

the number of faults in the roll of fabric : a discrete vector

x

the log of the length of the roll : a numeric vector

Details

The data are 32 observations on faults in rolls of fabric taken from Hinde (1982)
who used the EM algorithm to fit a Poisson-normal model.
The response variable is the number of faults in the roll of fabric and the explanatory variable is the log of the length of the roll.
