Dear Netters,
I have one problem I am not able to answer by myself. I'm working
on host-parasite interactions in insects ; and more precisely on
spatial distribution of both hosts and parasites. For several
reasons, I need to transform the host spatial distribution pat-
tern (which usually show a highly agretated structure) into an
uniform distribution, in both the x's and the y's direction. This
will allows me to accurately diescribe the characteristics of the
parasite distribution AT A STANDARDIZED HOST DISTRIBUTION.. So I
have the Xi-Yi coordinates of all the hosts, and I thus need a
transformation on these pairs of data.
If there is only one patch of hosts, the most obvious transforma-
tion is to take the ranks of the x's and the y's. However, for
more than one path such a simple transfomation does not work any
more.
Is there someone out there that can provide me any help in this?
Thanks in advance.
