Fit Bayesian multivariate GARCH models using 'Stan' for full Bayesian inference. Generate (weighted) forecasts for means, variances (volatility) and correlations. Currently DCC(P,Q), CCC(P,Q), pdBEKK(P,Q), and BEKK(P,Q) parameterizations are implemented, based either on a multivariate gaussian normal or student-t distribution. DCC and CCC models are based on Engle (2002) doi:10.1198/073500102288618487 and Bollerslev (1990). The BEKK parameterization follows Engle and Kroner (1995) doi:10.1017/S0266466600009063 while the pdBEKK as well as the estimation approach for this package is described in Rast et al. (2020) doi:10.31234/osf.io/j57pk. The fitted models contain 'rstan' objects and can be examined with 'rstan' functions.
