## Prerequisites {.unumbered}

::: callout-important
To use the `rethinking` you must install it as advised by Richard McElreath as described in [rethinking](https://github.com/rmcelreath/rethinking). You need to pay attention when it is done, but it works fine. Make sure you verify the installation with `example(stan_model, package = "rstan", run.dontrun = TRUE)` as described in the guides.
