adgR Documentation

Dataset related to average daily growth performance and abattoir findings in pigs commercial production.

Description

The case study dataset is about growth performance and abattoir findings in pigs commercial production in a selected set of 15 Canadian farms collected in March 1987.

Usage

adg

Format

An adapted data frame of the original dataset which consists of 341 observations of 8 variables and a grouping variable (farm).

AR

presence of atrophic rhinitis.

pneumS

presence of moderate to severe pneumonia.

female

sex of the pig (1=female, 0=castrated).

livdam

presence of liver damage (parasite-induced white spots).

eggs

presence of fecal/gastrointestinal nematode eggs at time of slaughter.

wormCount

count of nematodes in small intestine at time of slaughter.

age

days elapsed from birth to slaughter (days).

adg

average daily weight gain (grams).

farm

farm ID.

Details

When using the data to fit an additive Bayesian network, the variables AR, pneumS, female, livdam, eggs are considered binomial, wormcount Poisson, age and adg Gaussian. The variable farm can be used to adjust for grouping.
