WebApr 23, 2024 · In polynomial regression, you add different powers of the X variable ( X, X2, X3…) to an equation to see whether they increase the R2 significantly. First you do a linear regression, fitting an equation of the form ˆY = a + b1X to the data. Then you fit an equation of the form \hat {Y}=a+b_1X+b_2X^2\), which produces a parabola, to the data. WebLinear regression is used to model the relationship between two variables and estimate the value of a response by using a line-of-best-fit.
