Thanks for fixing the previous issue so quickly. Unfortunately, I ran into another issue on a different dataset. I have reduced the problem to the repex below:
df <- readr::read_csv(here::here("data_w_error.csv"))

Hi Dimitris,
Thanks for fixing the previous issue so quickly. Unfortunately, I ran into another issue on a different dataset. I have reduced the problem to the repex below:
Created on 2024-01-16 with reprex v2.1.0
Here's the stubborn dataset that yields the error: data_w_error.csv
Any idea what's going on? I noticed that Hbetas was a matrix of NaNs after the
numer_deriv_vec
call.I'm running version 0.9.2 of GLMMadaptive now on R 4.3.1.
