Dataset of Mid-Atlantic Highlands Fish

Description

This dataset was studied by Johnson and Hoeting (2011) for analyzing pollution tolerance in Mid-Atlantic Highlands Fish. Pollution intolerant fish were sampled, and several stream characteristics were measured to assess water quality at 119 sites in the Mid-Atlantic region of the United States. All covariates of the data had been standardized to have mean 0 and variance 1.

Usage

LAT

Latitude of the location.

ABUND

Fish abundance at given locations, the discrete response.

ORDER

Strahler stream order, a natural covariate measuring stream size.

DISTOT

Watershed area, a natural covariate.

ELEV

Elevation.

RD

Road density in the watershed, a variable reflecting stream quality.

DO

Concentration of dissolved oxygen in the stream at the sampling site, a stream quality variable.

XFC
