IslandSpArea: Species area relationship

In gpk: 100 Data Sets for Statistics Education

Description

4. Island biogeography is a branch of ecology, which discusses evolution and spread of species on Islands. One of the theories is that as area of island shrinks the number of species of animals living on the island declines, but probably not linearly. One model suggested is $sp= k*A^z$ where A is area and k, z are constants.

Usage

data(IslandSpArea)

Format

A data frame with 16 observations on the following 2 variables.

Area

Area of the island (Sq. Km)

Species

Number of species seen

Details

Nonlinear regression and transformation of variables may improve the linear regression model.
