One again, this method produces the same best fitting line. We can use the same methods with a larger problem. Example 6.4.4: Use the Solver Method on a Larger Data Set. NettetThe meaning of r 2. The value r 2 is a fraction between 0.0 and 1.0, and has no units. An r 2 value of 0.0 means that knowing X does not help you predict Y. There is no linear relationship between X and Y, and the best-fit line is a horizontal line going through the mean of all Y values.
