Now, let us see the formula to find the value of the regression coefficient. B 1 = b 1 = Σ [ (x i – x) (y i – y) ] / Σ [ (x i – x) 2 ]

NettetIn statistics, a regression equation (or function) is linear when it is linear in the parameters. While the equation must be linear in the parameters, you can transform the predictor variables in ways that produce curvature. For instance, you can include a squared variable to produce a U-shaped curve. Y = b o + b 1 X 1 + b 2 X 12.
