spatial covariance structure in glmmTMB
Hi Alice, Have you looked at the vignette on covariance structures? There's a section on spatial correlations. https://cran.r-project.org/web/packages/glmmTMB/vignettes/covstruct.html cheers, Mollie

Dear list,
I am fitting mixed effects models using the package glmmTMB to investigate
habitat use.
My current model has the form m1<-glmmTMB(count~waterdepth + temperature +
chl.conc + (1|individual), family=list(family="truncated_nbinom1",
link="log"), data=mydata)
I would like to add a spatial covariance structure based on geographic
coordinates (mydata$x and mydata$y).
However, I do not know how to modify my model formula to include a spatial
covariance structure. Does anyone have example code to show how this is
done?
Any help would be much appreciated!
