OzoneR Documentation

Los Angeles ozone pollution data, 1976


A data frame with 366 observations on 13 variables, each observation is one day


data("Ozone", package = "mlbench")


1 Month: 1 = January, ..., 12 = December
2 Day of month
3 Day of week: 1 = Monday, ..., 7 = Sunday
4 Daily maximum one-hour-average ozone reading
5 500 millibar pressure height (m) measured at Vandenberg AFB
6 Wind speed (mph) at Los Angeles International Airport (LAX)
7 Humidity (%) at LAX
8 Temperature (degrees F) measured at Sandburg, CA
9 Temperature (degrees F) measured at El Monte, CA
10 Inversion base height (feet) at LAX
11 Pressure gradient (mm Hg) from LAX to Daggett, CA
12 Inversion base temperature (degrees F) at LAX
13 Visibility (miles) measured at LAX


The problem is to predict the daily maximum one-hour-average ozone reading (V4).
