ozone: Data set of Ozone Data
In hlorenzo/outlierSIR: outlierSIR: Check for outliers in SIR models

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.
