Jan 13, 2015. We interpret the standardized coefficients as follows: a one standard deviation increase in Xk results in a b'k. the ANOVA table, we are interested in the Total sum of squares (SST), the regression sum of squares (SSR), and the error sum of squares (SSE; also known as the residual sum of squares).

The regression sum of squares for the model is equal to zero since this model does not contain any variables. Therefore: The sequential sum of squares for is:
