I think that you are mis-understanding the table (granted it's confusing): the mean is then a Frechet mean, using as a distance in the Frechet mean the distance of interest. This can be in general not completely trivial to code. > I was simply expected the distance function to be configurable as it is > with many other sklearn functions. Features in scikit-learn are pretty much implemented as people contribute them. It seem that nobody so far has needed this feature badly enough to contribute it.
