WebAn example. Let's return to our example with n = 4 data points (3 blue and 1 red): Regressing y on x and requesting the studentized residuals, we obtain the following software output: As you can see, the studentized residual (" TRES1 ") for the red data point is t4 = -19.7990. WebPoints that fall horizontally far from the line are points of high leverage; these points can strongly influence the slope of the least squares line. If one of these high leverage points does appear to actually invoke its influence on the slope of the line — as in cases (3), (4), and (5) of Example 8.3.2 — then we call it an influential point .
