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 more than a few predictor variables are used. Se hela listan på engineerexcel.com The polynomial regression is a statistical technique to fit a non-linear equation to a data set by employing polynomial functions of the independent variable. We can use the model whenever we notice a non-linear relationship between the dependent and independent variables. For those seeking a standard two-element simple linear regression, select polynomial degree 1 below, and for the standard form — $ \displaystyle f(x) = mx + b$ — b corresponds to the first parameter listed in the results window below, and m to the second.
