NettetHere's a process you might try. Find the point that is the closest to one corner. Then, find the point that is closest to the opposite corner. Connect those two points. Then, look at the line you draw and compare the rest of the points to it. If there are more points above the line than below it, then you might need to move the line up some. NettetResiduals to the rescue! A residual is a measure of how well a line fits an individual data point.

The x-axis on this plot shows the actual values for the predictor variable points and the y-axis shows the residual for that value. Since the residuals appear to be randomly scattered around zero, this is an indication that heteroscedasticity is not a problem with the predictor variable.
