Hi:

1) there are N points in the (x-y) space. Each point has
   has a distribution around it - call it error distribution
this distribution has an elliptic shape. its area is proportional to
   (1+abs(x)+abs(y))**2.

2) is there a measure to tell me something about separation between
   the distribution?

3) say instead of mapping (x,y) directly, we map (logx, logy).
this definitely reduces the error distribution but at the same
   time compress the distances between points. The measure
devised for 2) should be able to reflect this.


greatly appreciate any help.
