WebFor this post, I modified the y-axis scale to illustrate the y-intercept, but the overall results haven’t changed. If you extend the regression line downwards until you reach the point where it crosses the y-axis, you’ll find that the y-intercept value is negative! In fact, the regression equation shows us that the negative intercept is -114.3. WebAdjusted R-squared is only 0.788 for this model, which is worse, right? Well, no. We “explained” some of the variance in the original data by deflating it prior to fitting this model. Because the dependent variables are not the same, it is not appropriate to do a head-to-head comparison of R-squared.
