qThe quality of the linear regression can be analyzed using the “Analysis of Variance”.
qThe analysis separates the total variance of y  (Sy2) into the part that can be accounted for by the linear regression (b2Sx2) and the part that can not be accounted for by the regression (Se2):
q            Sy2 = b2Sx2 + Se2
