Dear community,
New in the development version of the ctmm package is the rsf.select() function, which you can install via:
remotes::install_github("ctmm-initiative/ctmm")
and then see the associated help file in:
?rsf.select
rsf.select() will perform model selection on multiple formula terms or raster covariates. This is recommended when using mean() to estimate population-level parameters, as, otherwise, unsupported parameter estimates can have ill-conditioned COV matrices, which mean() requires for calculation. Importantly, mean() does not require the same parameters to be selected on all individuals.
Best,
Chris
