Although polynomial regression can fit nonlinear data, it is still considered to be a form of linear regression because it is linear in the coefficients β 1, β 2, …, β h. Polynomial regression can be used for multiple predictor variables as well but this creates interaction terms in the model, which can make the model extremely complex if
