But I guess this is because it yields a better convergence for most integrands in practice. But why is that? Did they just do that on an empirical basis or is there a proper explanation? I am also not sure why this algorithm could be stable at all if you sum the squares instead of the absolute values. I tried to find a better rebinning algorithm but it seems to be impossible to find a stable one for integrands that are not factorizable. Why is it so good? | |
