%description
User-facing R functions are provided to parse, compile, test, estimate,
and analyze Stan models by accessing the header-only Stan library provided
by the 'StanHeaders' package. The Stan project develops a probabilistic
programming language that implements full Bayesian statistical inference
via Markov Chain Monte Carlo, rough Bayesian inference via 'variational'
approximation, and (optionally penalized) maximum likelihood estimation
via optimization. In all three cases, automatic differentiation is used to
quickly and accurately evaluate gradients without burdening the user with
the need to derive the partial derivatives.
