In this part we will compare our code to the results obtained by other methods to provide a proof of concept. Hereby, we employ published copolymerization data , for which confidence contours have been determined by van Herk et al. and Scott et al. respectively. In total, three different analysis are carried out whose data pairs are labeled A, B and C in table 3. Herbeby, case A is an individual copolymerization experiment, while C and B refer to the same experiment. B and C merely denote a switch in the reference monomer (monomer 1 or monomer 2), in order to prove the validity of our approach in comparison to Scott et al. The errors used for the analysis are constant relative errors, in accordance with the previously published works. In the dependent variable (F i ), we assume σ y,{A,B,C} /y = 0.05. For the error in the independent variable ( f i ), we neglect the error for the comparison to van Herk et al., but consider an error of σ x,{A,B} /x = 0.01 and for comparison to contours derived by Scott. This is due to the different considerations of the approaches, as van Herk does not account for errors in independent variables (see table ).
