Some thoughts about this article
2 - their aim is the calculate the percentage of all ingredients in a food product. This requires that one knows the total weight of the ingredients that went in.
2 - do they imply to use the energy as well. It is mentioned as part of the Big7. As this is dependent on the other nutrients, it will not offer new information.
2 - fig 1 one of the constraints is a bit strange (X1 > () > x6). Is that intentional?
2 - The German Nutrient Database (Bundeslebensmittelschlüssel) is used. Might be useful for us.
2.2 - they use the subingredients as well, but do not detail how that impacts the equations. They record the percentages as well. What do they mean by noncompositional ingredients?
- lpSolve - the they not explain how they set this up. It is a complex approach to linear equalities. I did not manage to get it working.
- Fitting of percentages;
- Fit fails, why;
- Missing discussion on the errors:
- Usefulness of measurement errors;
