Team Member: Josh, Liyou, Hamilton, Andrew

Findings

  • The best predictors for the auction price of a machine are Product Group, Product Size, YearMade, MachineHoursCurrentMeter, Age, auctioneer.

Methodology

  • The dataset contains 53 features of tractors and have more than 400,000 rows. Most of the features have high percentage of missing values.

  • Feature engineering includes filling NaNs with medians, transform datatype, calculate age of the tractor and create dummies for categorical variables.

  • Used linear regression model and the measurement of performance is Root Mean Squared Log Error (RMSLE).
