%description
Offers a flexible formula-based interface for building and training
Bayesian Neural Networks powered by 'Stan'. The package supports modeling
complex relationships while providing rigorous uncertainty quantification
via posterior distributions. With features like user chosen priors, clear
predictions, and support for regression, binary, and multi-class
classification, it is well-suited for applications in clinical trials,
finance, and other fields requiring robust Bayesian inference and
decision-making. References: Neal(1996) <doi:10.1007/978-1-4612-0745-0>.
