Types Linear regression vs Polynomial regression Demo A centre of excellence in science and technology enriched with GNH values  College of Science and Technology CST Royal University of Bhutan Introduciton In linear regression, the relationship is considered to be linear Data may not follow the linear pattern all the time Straight line may not represent the relationship Thus, Polynominal regression, Accepts curved or non-linear relationsips A centre of excellence in science and technology enriched with GNH values  College of Science and Technology CST Royal University of Bhutan What is it? is a form of regression analysis that models the relationship between X and Y as an nth degree polynomial function. In other words, it extends the concept of linear regression to capture nonlinear relationships between variables.
