Susan,
I've been doing regressions of all flavors with BBS data. However, I've
stopped using SAS and I've switched to R. I don't think you can get
either to calculate delta AIC but that's just AICmodel - AICmin correct?
Maybe you can get deltaAIC with stepAIC in R and you might be able to do

Brad,
Have you checked out R? It is an open source program that does just
about everything SAS does if not more.
You can dowload it and get documentation from http://www.r-project.org/
I've switched to R from SAS. It hasn't been easy but so far it has been
worth it.
Best,

Greetings,
I'm attempting to model the spatial distrubution of avian species
richness (SR) across a gradient of distrubance. SR was divided into
several groups (all, residents, short-, and long-distance migrants) and
analyzed separately. I used point counts (0.8 km) apart to get the
species rich
Euan,
Most sampling designs, regardless of geographic location, are taxon
specific so it would be useful to know what group your friend is working
with. Always good to run some analyses with preliminary data. For
animals this would involve SR repeated sampling to estimate both
