WebFeb 19, 2024 · The formula for a simple linear regression is: y is the predicted value of the dependent variable ( y) for any given value of the independent variable ( x ). B0 is the intercept, the predicted value of y when the x is 0. B1 is the regression coefficient – how much we expect y to change as x increases. x is the independent variable ( the ... WebR-squared tells us what percent of the prediction error in the y y y y variable is eliminated when we use least-squares regression on the x x x x variable.
