- The
relativevalue is the weighted sum of the differences with weight given by the inverse of the current value of the statistic. - The
absolutevalue is therelativevalue divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

Given a functor `F : C ⥤ D`, we define a functor `F.partialLeftAdjoint : F.PartialLeftAdjointSource ⥤ C` which is defined on a certain full subcategory of `D`. It satisfies similar properties to the right adjoint of `F` (if this existed). We show that the domain of definition of this partial right adjoint is stable under certain limits. This dualises #17388, I came across this while formalising Proposition 4.3.4 of Emily Riehl's Category Theory in Context. I will also work on formalising Proposition 4.3.6, which is the bifunctor version of this. Co-authored-by: grhkm21 <83517584+grhkm21@users.noreply.github.com>
