Hello,

I'm searching for a method which maps variables of this kind of table, see below, to 2-dimensional space, like in multidimensional scaling. However, this table is asymmetric: for example, variable T1 affects T2 more than T2 affects T1(0.41 vs. 0.21).

> DEPTABLE

     T1 T2 T3 T4

T1 0.00 0.41 0.24 1.18
T2 0.21 0.00 0.46 0.12
T3 0.80 0.89 0.00 0.20
T4 0.09 1.04 0.17 0.00

Any suggestions? Something like gplot+mds+weighted arrays?
