The regression line is the line that makes SSres a minimum. Because SSres is a minimum
Chapter 8, Problem 6(choose chapter or problem)
The regression line is the line that makes SSres a minimum. Because SSres is a minimum, the regression line is the best-fitting linear function. Show that SSres would be greater for the function y2 = 2.1x + 3.5 that has y-intercept 3.5 instead of 3.4 and also greater for the function y3 = 2.2x + 3.4 that has slope 2.2 instead of 2.
