- 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.
