The file constructed colimits of functors F : J ⥤ MonCat.{v} under the assumption that J is a SmallCategory.{v}. It turns out that the smallness conditions on the Hom types of J is unnecessary and can simply be removed.

  • The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
  • The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

The file constructed colimits of functors `F : J ⥤ MonCat.{v}` under the assumption that `J` is a `SmallCategory.{v}`. It turns out that the smallness conditions on the `Hom` types of `J` is unnecessary and can simply be removed.
