Using the data provided, determine the VIF for each independent variable in the model. Is there reason to suspect the existence of collinearity? Click the icon to view the data. Determine the VIF for each independent variable in the model. VIF2 (Round to three decimal places as needed.) Is there reason to suspect the existence of collinearity? A- Yes. The VIF for each independent variable is less than 5. 0 B. No. The VIF for each independent variable is less than 5. O C. Yes. The VIF for each independent variable is greater than 5. O D. No. The VIF for each independent variable is greater than 5Explanation / Answer
Correlation between MPG and Horsepower = -0.8249
VIF1 = 1/(1-R2) = 1/(1-(-0.82492)) = 1/(1-0.6805)= 1/0.3195 = 3.129
Correlation between MPG and Weight = -0.8596
VIF2 = 1/(1-R2) = 1/(1-(-0.85962)) = 1/(1-0.7389)= 1/0.2611 = 3.829
No, the VIF of each independent variable is less than 55.
