# variables explicatives sont Hour, Traffic et Wind.
#
# Hour: 	hour of the day, from midnight to midnight
# CO: 		average summer weekday CO concentration (parts per million)
# Traffic: 	average weekday traffic density (traffic count/traffic speed)
# Wind: 	average perpendicular wind-speed component,
#                  wind speed x cos(wind direction - 235 degrees)
