Data collected in an experiment in which rats were injected with a dose of a drug approximately proportional to body weight. At the end of the experiment, the animal's liver was weighed, and the fraction of the drug recoved in the liver was recorded. The experimenter expected the response to be independent of the predictors.
This data frame contains the following columns:
BodyWt of the rat
LiverWt measured after sacrifice
Dose, roughly proportional to body weight
dose of drug recovered after sacrifice of the animal
