Imagine you have a dataset where the relationship between the variables is cubic. What type of regression would be appropriate, and why?

  • Linear Regression
  • Logistic Regression
  • Polynomial Regression of degree 3
  • Ridge Regression
Since the relationship between the variables is cubic, a Polynomial Regression of degree 3 would be the best fit. It will model the cubic relationship effectively, whereas other types of regression would not capture the cubic nature of the relationship.
