Equation for the linear regression
WebLinear Regression. Equation. You may be interested in whether the amount of caffeine intake (predictor) before a run can predict or explain faster running times (outcome), or … WebIn 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.
