Homework: variable selection

• With the boston data, we found that the first feature we should include is LSTAT, please describe the reason.
• What's the correlation of LSTAT with price? (you can read the number from the lecture note, or compute yourself)
• After including this feature, which next feature should we add that gives the highest F-to-enter score?
• What's the correlation between that next feature and the price?
• Provide the final model you obtain using a proper variable selection method.
