Lakes: Lakes Data

Description

Lakes data represent a multivariate predictor nonlinear model.

Usage

data(Lakes)

Arguments

Format

The format is:data.frame chr "Lakes"

  • tn: mean annual total nitrogen concentration, response variable.

  • nin: average influence nitrogen concentration, predictor variable one.

  • tw: water retention time, predictor variable two.

Details

Lakes data is collected from 29 lakes in Florida by United States Environmental Protection Agency (1978). Stromberg (1993) has identified observations 10 and 23 as outliers. The data presents the relationship between the mean annual total nitrogen concentration, TN, as the response variable and the average influence nitrogen concentration, NIN, and water retention time, TW, as predictors.
