[list] [*] 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 [b]m[/b] to minimize [b]SAE[/b] or [b]SSE[/b]. Notice that the number above and below the line can be equal even when the line is a poor approximation to the data. [/list]
Does the Linear Regression Line minimize [b]SAE[/b] or [b]SSE[/b]? Can you move the points to get either [b]SAE[/b] or [b]SSE[/b] to be zero?
