Visualizing Linear Regression
- Richard Voss
- Select and move individual points to see their effect on the X and Y means, Quadrant counts, or Linear Regression Line.
- Show the Line through middle and adjust slope m to minimize SAE or SSE. Notice that the number above and below the line can be equal even when the line is a poor approximation to the data.
Does the Linear Regression Line minimize SAE or SSE? Can you move the points to get either SAE or SSE to be zero?
