BRMS compilation error for certain group level effect specifications

Interfaces brms

  • Operating System: Ubuntu 4.15.0-1035-aws
  • brms Version: 2.8.0
  • rstan Version: 2.18.9

I get a compilation error using brms for some models on a dataset but not others. See below:

    // Works
    out <- brms::brm(r | trials(n) ~ t, 
                        control = list(adapt_delta = 0.99), cores = 4, iter = 5000, family = binomial(), data =long_dat)

    //Works
    brms::brm(r | trials(n) ~  t + (-1 + t | study_id), 
                        control = list(adapt_delta = 0.99), cores = 4, iter = 5000, family = binomial(), data = long_dat)


    //Error
    brms::brm(r | trials(n) ~  t + (1 + t | study_id), 
                        control = list(adapt_delta = 0.99), cores = 4, iter = 5000, family = binomial(), data = long_dat)

I’m assuming I’m making an error somewhere? Tried installing stanheaders. Could it be a packrat issue?

I don’t know what exactly is happening but perhaps @bgoodri does?

I had a similar problem, but it was weirdly due to the working directory. Are you using some Box folder, or a network-based/aware FS directory as a working directory?

I have no idea why, but when I was using a Box directory (using rclone to sync), some brms/stan models would compile, others wouldn’t. I moved those out of the Box hierarchy, changed the working directory, and it was fine.

Hmmm, we are using RStudio Server hosted on an AWS box but my working directory is just my user directory on that system so I don’t think this is the issue?

This is similar to the question I just posted. I’m using Debian and receiving the exact same error.

If you put verbose = T in the call to Stan, what is the first error: notification in the output? You might need to save the result to a txt file first using capture.output(stan(..., verbose=T), 'filename.txt') to read the error message.
