Relative liver weights
Data from a toxicity trial with male Wistar rats: Relative liver weights in a negative control group and in 4 dose groups with an increasing dose of an active treatment. After treatment the relative liver weights of the rats were computed.
data(liver)
A data frame with 38 observations on the following 2 variables.
dosageA numeric vector indicating the dose/control group.
weightA numeric vector containing the relative liver weights.
The objective is to test if the active treatment influences the liver weight of the rats.
