Stan_surv in rstanarm

Hi all,

I am using R 4.1.2 and trying to fit a model with stan_surv. I followed the instruction to install rstanarm from

install.packages("rstanarm", repos = c("", getOption("repos")))

However, I still cannot see the function stan_surv. Did I miss any steps?

My understanding is that you need to use the developer version of rstanarm from github.
The code below should work but I’m having problems with the install in windows

devtools::install_github(“stan-dev/rstanarm”,ref = “feature/survival”, build_vignettes = FALSE)
