Fish {gpk}

Fish species interaction

Description

Brook trout and cut-throat tout are two species of stream fish. If they compete with each other then high density of one may suggest absence of the other. If they are symbiotic, high density of one may promote the other. These data are from streams. Typical mountain streams are about 2.5m wide. (Kilograms per hectare is a conventional density measurement used in lakes) Can we predict presence/absence of Yellowstone Cutthroat trout as a function of density (kg/ha) of Brook trout?

Usage

Format

A data frame with 24 observations on the following 2 variables.

BKT

density of Brook trout (kg/ha)

YSC

Presence/ absence of Yellowstone Cutthroat trout

Details

Use the logistic regression model.
