May 06, 2008 · If in a regression analysis the explained sum of squares is 75 and the unexplained sum of square is 25, r2 = 0.33. ____T___ 19. In general, the smaller the dispersion of observed points about a fitted regression line, the larger the value of the coefficient of determination.

The following example illustrates why this definition is the sum of squares. Example Sum of Squared Errors Matrix Form. To show in matrix form, the equation d’d is the sum of squares, consider a matrix d of dimension (1 x 3) consisting of the elements 2, 4, 6. Also, recall by taking the transpose, the rows and columns are interchanged.

Extra Sum of Squares from Several Variables Extra sums of squares involving two extra X variables, such as SSR(X2, X3| X1), have two degrees of freedom associated with them. This follows because we can express such an extra sum of squares as a sum of two extra sums of squares, each associated with one degree of freedom.

It is immaterial as to which group gets the positive or negative sign since it is the sum of squares of the comparison that is used in the F-test. The coefficients for any comparison should be reduced to the smallest possible integers for each calculation.
