Ozone Interaction Data

Description

The data consists of 366 readings of maximum daily ozone measured in the Los Angeles basin. After removing missing values, the original data has been expanded to include all pairwise interactions, as well as B-spline basis functions (6 degrees of freedom), for each of the original 12 variables (9 meteorlogical variables and 3 variables recording date of measurement: month, day of the month, and day of week). In total, the modified data has 203 observations and 134 variables. The outcome is ozone.
