A collection of R and C++ functions, which assist in the Bayesian inference of vector autoregressive (VAR) and vector error correction (VEC) models.
The package bvartools implements some common functions used for Bayesian
inference for linear, multivariate time series models. It should give researchers
maximum freedom in setting up MCMC algorithms in R and keep calculation time
limited at the same time. This is achieved by implementing posterior simulation
functions in C++. Its main features are
The bvar and bvec functions collect the output of a Gibbs sampler
in standardised objects, which can be used for further analyses.
Further functions such as predict, irf, fevd for forecasting,
impulse response analysis and forecast error variance decomposition, respectively.
Computationally intensive functions - such as for posterior
simulation - are written in C++ using the RcppArmadillo package of Eddelbuettel
and Sanderson (2014).
