Air Pollution in US Cities
Description
Air pollution data of 41 US cities.
Usage
data("USairpollution")
Format
A data frame with 41 observations on the following 7 variables.
SO2SO2 content of air in micrograms per cubic metre.
tempaverage annual temperature in Fahrenheit.
manunumber of manufacturing enterprises
employing 20 or more workers.
populpopulation size (1970 census); in thousands.
windaverage annual wind speed in miles per hour.
precipaverage annual precipitation in inches.
predaysaverage number of days with precipitation per year.
Details
The annual mean concentration of sulphur dioxide, in micrograms per cubic metre, is a
measure of the air pollution of the city. The question of interest here is what
aspects of climate and human ecology as measured by the other six variables in the
data determine pollution?
