What was built

    Exploratory analysis finds missing values coded as -200 and compares possible targets. I chose CO(GT). Simple and multiple linear regression are compared with decision-tree regressors. A tree tuned with RandomizedSearchCV (400 candidates, 5-fold) reaches a test R-squared of 0.843.
