A global variable that defines the default cache directory for Stan models used by the sccomp package. This directory is used to store compiled Stan models to avoid recompilation on subsequent runs.
Details
The cache directory is set to ~/.sccomp_models by default. This location is used by
various sccomp functions to store and retrieve compiled Stan models, improving performance
by avoiding unnecessary recompilation of models that have already been compiled.
Users can override this default by specifying a different cache directory in function calls
that accept a cache_stan_model parameter.
