SCENARIO 15-5
What are the factors that determine the acceleration time (in sec. )from 0 to 60 miles per hour of a car? Data on the following variables for 171 different vehicle models were collected:
Accel Time: Acceleration time in sec.
Cargo Vol: Cargo volume in cu.ft.
HP: Horsepower
MPG: Miles per gallon
SUV: 1 if the vehicle model is an SUV with Coupe as the base when SUV and Sedan are both 0
Sedan: 1 if the vehicle model is a sedan with Coupe as the base when SUV and Sedan are both 0
The coefficient of multiple determination ( R 2j)for the regression model using each of the 5 variables X j as the dependent variable and all other X variables as independent variables are,respectively,
0.7461,0.5676,0.6764,0.8582,0.6632.
-Referring to Scenario 15-5,what is the value of the variance inflationary factor of SUV?
