Hello all,

I'm new in this list, so I'm sorry if I'm repeating any subject.

I was thinking if it's possible to us the grid cell values of an animal
Utilization Distribution (UD) as response variable in a mixed model,
relating to e.g. distance to highway.

This is because I want to model the space use of a group of animals
(martens) in relation to distance to a highway, to see if there's any effect
on higher/lower use intensity with hwy distance.

Using the nlme package, I thought I could do:

mod <- lme(fixed = UD~Dist.hwy,  random=~1|Marten, correlation =
corGaus(form = ~ x + y|Marten), method = "ML", data = mydata)

Would this be correct?

Thanks in advance for your help
