The Gini Coefficient is invariant under scaling, but not under
translation. Standard deviation is invariant under translation, but
iminate the strongly defeated candidates, and then use random ballot to
eliminate all but N of the remaining candidates.
Something like that.
Keep us going on this!

Hello all,
a week ago I suggested using social welfare functions (such as the Gini welfare
function) to evaluate election methods.
Now I did some simulations of the following kind:
1. Draw n (e.g. 1000) voter and c (e.g. 3) candidate positions from a
d-dimensional (e.g. 2) standard normal dist
