ZIB models
...and landscape variables, which
I've been testing in smaller groups.
> zib.out<-obs.error(y=painted,m=numvis,bp=zvars,pcovar=7)
I get the following error message, with all species, all variable
groups, standardized and unstandardized data...
Error in optim(par = rnorm(pcovar + qcovar), fn = obs.error.LL, method =
"L-BFGS-B", :
L-BFGS-B needs finite values of fn
I have a large sample size, so we're not sure that this is related to a
convergence problem, but we can't figure out what this error means.
Thank you,
