WebThe regression sum of squares is 10.8, which is 90% smaller than the total sum of squares (108). This difference between the two sums of squares, expressed as a fraction of the total sum of squares, is the definition of r 2.In this case we would say that r 2 =0.90; the X variable "explains" 90% of the variation in the Y variable.. The r 2 value is formally known …
