Analysis of variance for regression

Analysis of variance for regression (four strains, strain differences ignored)... 

The individual results for the duplicated star points and the extra centre point were listed in table 5.2. These, when added to the factorial design of table 4.2, make up the duplicated central composite design. Analysis of variance for regression may be carried out on the complete data set of the composite design for the second degree model (20 data). The results are summarised in table 5.5. 

An value near 1 indicates that all residuals are small and that the fit is good. An elaborate treatment regarding R and the analysis of variance for regression analysis is beyond the scope of the present discussion.
