Hi - yes that's the point of the (nonlinear) transformation - instead of being bounded as r (-1 : 1) Z is (-inf : inf). The closer r gets to one, Z really takes off...into the tail of the Gaussian.

I understand that if I use, e.g. netmats=nets_netmats(ts,1,'corr'), then the "1" will facilitate a Fisher r to z transform. However when I compare the untransformed matrix of r values to the transformed matrix, I see that, for example, r=.5155 gets converted to z=5.1373, and r=.9290 gets converted to 14.8730! How can the z-scores be so high? Am I interpreting these results incorrectly somehow? > > Thanks very much! --------------------------------------------------------------------------- Stephen M.
