WebApr 23, 2024 · The equation for the regression line is usually expressed as Y ^ = a + b X, where a is the Y intercept and b is the slope. Once you know a and b, you can use this equation to predict the value of Y for a given value of X. For example, the equation for the heart rate-speed experiment is rate = 63.357 + 3.749 × speed. WebFrom our linear regression analysis, we find that r = 0.9741, therefore r 2 = 0.9488, which is agrees with the graph. You should now see that the Excel graphing routine uses linear regression to calculate the slope, y-intercept and correlation coefficient.

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. fitlinearWebTo clear the graph and enter a new data set, press "Reset".
