This is a real data set which was used in \"Leo Breiman and Jerome H. Fi'iedman (1985), Estimating optimal transformations for multiple regression and correlation, JASA, 80, pp. 580-598\". The problem is to predict the daily maximum one-houraverage ozone reading in Los Angeles. The original data set can be found in R under mlbench package with the name \"Ozone\". The data set is provided along with this lab in the le ozone . txt. There are 12 predictor variables in the original data set. I have removed the categorical variables and the entries with missing information which leaves you with 9 predictor variables (X) and 203 observations. Y Daily maximum one-hour-average ozone reading X1 500 millibar pressure height (m) measured at Vandenberg AFB X2 Wind speed (mph) at Los Angeles International Airport (LAX) X3 Humidity ('70) at LAX X4 Temperature (degrees F) measured at Sandburg, CA X5 Temperature (degrees F) measured at El Monte, CA X6 Inversion base height (feet) at LAX X7 Pressure gradient (mm Hg) from LAX to Daggett, CA X8 Inversion base temperature (degrees F) at LAX X9 Visibility (miles) measured at LAX You are to come up with the best model that predicts the daily maximum one-houraverage ozone reading in Los Angeles using any combination of tools you have learned in this class so far. Consider the use of quadratic terms but no further. It is natural that people may come up with almost equally useful different models. You will be assessed on based on not an ultimate truth but rather how you approach the problem, how correctly you implement the covered methods and how you justify your actions
