rtrout: Weights of rainbow trout

In GLMsData: Generalized Linear Model Data Sets

Weights of rainbow trout

Description

Weights of rainbow trout at various doses of dca

Usage

data(rtrout)

Format

A data frame containing 96 observations with the following 2 variables.

Weight

the weight of the rainbow trout, in grams; a numeric vector

Dose

the dose of 3, 4-dichloroaniline (dca), in micrograms per litre; one of 0 (control), 19, 39, 39, 71, 120, or 210

Details

The data give the weight of 95 rainbow trout after exposure to dca for 28 days (note that one observation is missing at a dose of 39). The aim of the study was to “determine the concentration level which causes 25% inhibition [i.e. weight loss] from the control” (Maul, p. 161).
