Hi all, I am new to brm() and wanted to use it to run a model for my analyses. I do get the following error-message as I call brm():
Stan model ‘anon_model’ does not contain samples.
Error in do.call(rbind, sampler_params) : second argument must be a list
I m running the code on an M2 chip and sonoma as operating system. I installed the scode CLI and gfortran using the macrtools package.
I then installed the required packages from source. My model runs on a windows system using rtools perfectly fine. But I get the error above.
brm( formula, data = df1, family = cumulative("probit"), prior = prior_spec, chains = 4, iter = 4000, warmup = 1000, control = list(adapt_delta = 0.80, max_treedepth = 10), save_all_pars = TRUE, init = 0 , sample_prior = TRUE, seed = 42, file = paste("model_fits", paste0(model_name, ".r"), sep = "/") )
- Operating System: macos 14.0
I am looking forward to any help on this. I think it is likely that my environment is not setup properly to run brm(). I will add more specific information if needed.
