Model_parameters with standardize = 'refit' - suddenly stopped working without any error
Hello, I have been running some stats on the same dataset with the same code and everything worked perfectly. However, today I updated R (now 4.2..0) and RStudio (2022.02.3+492), installed all the packages and suddenly, model_parameters with standardize = 'refit' stopped working. No error, no anything - it keeps converging ad infinitum. Weirdly, when I try to do standardize = 'basic', it works. On another laptop, I tried redoing everything, and it only works if I first try to run model_parameters with standardize = 'basic', and then switch back to 'refit'.
I am completely clueless about what the issue might be... Do you perhaps, have any idea? Thanks in advance! Kind regards
Fix that worked for me: I uninstalled merDeriv package and it started working again. Maybe it might be of help for anyone else encountering such an issue.
We improved the calculation of standard errors and confidence intervals for the random effects parameters from mixed models. I guess, this is the issue you ran into (because now we have CIs of random effects even for more complex models, which is of course more time consuming than not computing any CIs). However, instead of uninstalling the merDeriv package, you can also set effects = "fixed" and random effects parameters and their CIs are not included.
Do you have a reproducible example, so we might check if we can solve this problem from our side?
Short update: you can also use ci_random = FALSE to explicitly suppress calculation of confidence intervals for random effects.
