Compared Linear Regression with Tuning Parameter

• ElasticNet Regression
• Lasso Regression
• Ridge Regression
• Linear Regression Evaluation Metrics using MAE and RSquare

Summary(1) = The Four Regression Models can do minimize overfitting rate but elastic net is selected because has smaller MAE.

Summary(2) = Variables Important which is trip_distance, location, and tip_amount
