%description
Efficient methods for Bayesian inference of state space models via Markov
chain Monte Carlo (MCMC) based on parallel importance sampling type
weighted estimators (Vihola, Helske, and Franks, 2020,
<doi:10.1111/sjos.12492>), particle MCMC, and its delayed acceptance
version. Gaussian, Poisson, binomial, negative binomial, and Gamma
observation densities and basic stochastic volatility models with
linear-Gaussian state dynamics, as well as general non-linear Gaussian
models and discretised diffusion models are supported. See Helske and
Vihola (2021, <doi:10.32614/RJ-2021-103>) for details.
