Description
Summary:
Hello, I was hoping to see if ranef() is available in any branch (or will be soon) for multilevel stan_surv objects? The documentation states that it is there but calling it errors out (I'm on rstanarm 2.19.1):
> ranef(multilevel_model)
Error: This method is for stan_glmer and stan_lmer models only.
Traceback:
1. ranef(multilevel_model)
2. ranef.stanreg(multilevel_model)
3. .glmer_check(object)
4. stop("This method is for stan_glmer and stan_lmer models only.",
. call. = FALSE)
In case it's helpful, here's the model formula:
Surv(time_to_status_days_float, Expired) ~ treatment + Sex + age_ordinal + DNR + (1 | LocationName)
RStanARM Version:

Research direction
Start by tracing ranef.stanreg through .glmer_check, using the reported stan_surv model and error as the reproduction case. Compare the existing stan_glmer and stan_lmer handling with the stan_surv path. Done means the documented ranef() call no longer raises this model-type error for a multilevel stan_surv object.
