Description

112 daily measurements of meteorological variables (windspeed, temperature, rainfall, cloudiness) and ozone concentration recorded in Rennes (France) during the summer 2001. In this study, an individual is a day. Thirteen variables were measured: 11 numerical variables and 2 categorical variables with 2 or 4l evels. There is no missing values. In more detail, the variables are:

maxO3

maximum of daily ozone concentration measured in gr.m-3

T9, T12, T15

daily temperatures measured in degree Celsius at 9, 12 and 15h (numerical variables called temperature variables hereafter)

Ne9, Ne12, Ne15

cloudiness measured at 9, 12 and 15h (numerical variablescalled cloudiness variables hereafter)

Vx9, Vx12, Vx15

wind speed (E-W component) measured at 9, 12 and 15h (numerical variables called wind variables hereafter)

maxO3v

maximum concentration of ozone measured the day before

vent

wind direction measured at 12h (categorical variable with four categories)

pluie

occurrence or not of rainfall (categorical variable with two categories)

The initial objective is to explain the maximum of daily ozone concentration (the response variable is thusmaxO3) by the 10 numerical variables available (T9, T12, T15, Ne9, Ne12, Ne15, Vx9, Vx12, Vx15 and maxO3v). The twocategorical variables vent and pluie are not used in this study.
