Eg: Code:  # norm 1.023739e-12 alpha -6.751675 e 5.557e-11 rroots 5 skew 942118.35, size 8.466e-13, alpha -6.752, combined = 5.557e-11 rroots = 5 alpha, e/combined and rroots match, but does the norm relate to the size score? The ones I've looked at norm is a bit larger than the size, but I don't know if that's always true. Chris

For the first one, smaller is better, but for the second one larger is better. Last fiddled with by jasonp on 2015-09-13 at 02:25
