+A data frame with 366 observations on 13 variables, each observation is one day
+Usage
+data(Ozone)
+Format
+	Month: 1 = January, ..., 12 = December
+	Day of month
+	Day of week: 1 = Monday, ..., 7 = Sunday
+	Daily maximum one-hour-average ozone reading
+	500 millibar pressure height (m) measured at Vandenberg AFB
+	Wind speed (mph) at Los Angeles International Airport (LAX)
+	Humidity (%) at LAX
+	Temperature (degrees F) measured at Sandburg, CA
+	Temperature (degrees F) measured at El Monte, CA
+	Inversion base height (feet) at LAX
+	Pressure gradient (mm Hg) from LAX to Daggett, CA
+	Inversion base temperature (degrees F) at LAX
+	Visibility (miles) measured at LAX
+Details
+The problem is to predict the daily maximum one-hour-average ozone reading (V4).
