1 ESTIMATION IN R The R function lm is used to fit linear (regression) models. 2 EXAMPLE 1: FUEL EFFICIENCY OF AUTOMOBILES A data set on the fuel efficiencies of 38 cars (taken from Abraham and Ledolter, 2006) is used as an illustration. We try to model the fuel efficiency, measured in GPM (gallons per 100 miles), as a function of the weight of the car (in 1000 lb), cubic displacement (in cubic inches), number of cylinders, horsepower, acceleration (in seconds from 0 to 60 mph), and engine type (V-type and straight (coded as 1)).

The data set includes sale prices and vehicle characteristics of 1436 used Toyota Corollas. The objective here is to predict the sale price of a used automobile. ”] Variable Id Model Price Age_08_04 Mfg_Month Mfg_Year KM Fuel_Type HP Met_Color Color Automatic CC Doors Cylinders Gears Description Record_ID Model description Offer price in EUROs Age in months as in August 2004 Manufacturing month (1–12) Manufacturing year Accumulated kilometers on odometer Fuel type (petrol, diesel, CNG) Horsepower Metallic color (Yes=1, No=0) Color (blue, red, gray, silver, black, and so on) Automatic (Yes=1, No=0) Cylinder volume in cubic centimeters Number of doors Number of cylinders Number of gear positions 48 STANDARD LINEAR REGRESSION Quarterly_Tax Weight Mfr_Guarantee BOVAG_Guarantee Guarantee_Period ABS Airbag_1 Airbag_2 Airco Automatic_airco Boardcomputer CD_Player Central_Lock Powered_Windows Power_Steering Radio Mistlamps Sport_Model Backseat_Divider Metallic_Rim Radio_cassette Parking_Assistant Tow_Bar Quarterly road tax in EUROs Weight in kilograms Within manufacturer’s guarantee period (Yes=1, No=0) BOVAG (Dutch dealer network) guarantee (Yes=1, No=0) Guarantee period in months Anti-lock brake system (Yes=1, No=0) Driver airbag (Yes=1, No=0) Passenger airbag (Yes=1, No=0) Airconditioning (Yes=1, No=0) Automatic Airconditioning (Yes=1, No=0) Board computer (Yes=1, No=0) CD player (Yes=1, No=0) Central lock (Yes=1, No=0) Powered windows (Yes=1, No=0) Power steering (Yes=1, No=0) Radio (Yes=1, No=0) Mist lamps (Yes=1, No=0) Sport model (Yes=1, No=0) Backseat divider (Yes=1, No=0) Metallic rim (Yes=1, No=0) Radio cassette (Yes=1, No=0) Parking assistance system (Yes=1, No=0) Tow bar (Yes=1, No=0) For this particular illustration, we do not use all variables.
