I am running a stan_glmer model using a dataset. The model ran fine. However, after I recompiled it several times, the R session aborted. When I initiated a new session, the model is running super slow in both Rstudio and R. I tried to clear the environment and reinstall the rstanarm package, and restart laptop, but non of it worked. I am working on Mac OS system. I am wondering if anyone could point me in a direction on how to figure out where the problem lies? Thank you so much!!
Thank you for your reply! My Mac OS version is 10.14.6, R version is 4.0.3, RStudio version is 1.4.1103, and rstanarm version is 2.21.1. There is no error message when running the stan_glmer after it aborted the other time. Thank you for your help!
I am trying to implement a mixed effect model, and I am not sure how to implement it using stan_lm. I tried stan_lmer, and it still runs pretty slow. I am not sure if this will help, but I also wrote a model using rstan, and this model works fine.
I am using a toy dataset, with 2 levels and 24 observations in total. Thank you again for your help!
