%description
Fit Bayesian time series models using 'Stan' for full Bayesian inference.
A wide range of distributions and models are supported, allowing users to
fit Seasonal ARIMA, ARIMAX, Dynamic Harmonic Regression, GARCH, t-student
innovation GARCH models, asymmetric GARCH, Random Walks, stochastic
volatility models for univariate time series. Prior specifications are
flexible and explicitly encourage users to apply prior distributions that
actually reflect their beliefs. Model fit can easily be assessed and
compared with typical visualization methods, information criteria such as
loglik, AIC, BIC WAIC, Bayes factor and leave-one-out cross-validation
methods. References: Hyndman (2017) <doi:10.18637/jss.v027.i03>; Carpenter
