WebAug 26, 2024 · When you estimate a linear model without constant, you essentially "force" the estimated function to go through the ( 0, 0) coordinates. y = β 0 + β 1 x. y = 0 + β 1 x. So when x = 0, y will be 0 as well. You should not only look at R 2 since R 2 often will go up when you have no intercept.
