The so called sum of squares of the residuals is computed by
summing the squares of the observed data with the data of the fitted
regression model.

The complete analysis of variance table is shown in
Table 3.12. In the row `regression' the degree of freedom (df) and
the sum of squares and the estimated mean square of the fitted model
and in the next row, the `residual', the values for the difference of the
calculated and observed data are listed.
The values of F, R2, and RA2 from the first row are described later.
The last row, `total', holds the sum of squares of the observed data.
