Dear All,
I have a collections of spatial data. I have to analyze pairs of these
point patterns to test their spatial interaction. I was moving towards
the cross K Ripley's function. The problem, however, are the following:
1) What is the best way to get a single real value that represents the
interaction "power"?
2) How to obtain a value that even allows me to rank the pairwise
point patterns according to their interaction "power"?
PS: I have to perform the same analysis for temporal interaction and
spatio-temporal interaction.
Thanks in advance for your help

I don't believe that there is any (possible) answer to your question. I
would be
happy to be corrected in this regard.
What do you mean by ``interaction "power" ''?
As far as I know, if the temporal direction is to be treated differently
from spatial
dimensions, then there is no appropriate analogue of the K function
available. So
you cannot attack ``temporal interaction and spatio-temporal
interaction'' in this
way.
I believe that you need to formulate your goals much more clearly and
precisely.
If your goals can be so formulated then it may be possible to develop
some techniques
to achieve them. However my guess is that such development would
constitute a
major research undertaking.
cheers,
Rolf Turner
