%description
Efficient algorithms for Bayesian estimation of Structural Vector
Autoregressive (SVAR) models via Markov chain Monte Carlo methods. A wide
range of SVAR models is considered, including homo- and heteroskedastic
specifications and those with non-normal structural shocks. The
heteroskedastic SVAR model setup is similar as in Woźniak & Droumaguet
(2015) <doi:10.13140/RG.2.2.19492.55687> and Lütkepohl & Woźniak (2020)
<doi:10.1016/j.jedc.2020.103862>. The sampler of the structural matrix
follows Waggoner & Zha (2003) <doi:10.1016/S0165-1889(02)00168-9>, whereas
that for autoregressive parameters follows Chan, Koop, Yu (2022)
<https://www.joshuachan.org/papers/OISV.pdf>. The specification of Markov
switching heteroskedasticity is inspired by Song & Woźniak (2021)
<doi:10.1093/acrefore/9780190625979.013.174>, and that of Stochastic
Volatility model by Kastner & Frühwirth-Schnatter (2014)
<doi:10.1016/j.csda.2013.01.002>.
