Graphing regression line
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. WebThe graph of the line of best fit for the third-exam/final-exam example is as follows: The least squares regression line (best-fit line) for the third-exam/final-exam example has the equation: ^y = −173.51+4.83x y ^ = − 173.51 + 4.83 x. Remember, it is always important to plot a scatter diagram first.
