Estimation of Bayesian Global Vector Autoregressions with different prior setups and the possibility to introduce stochastic volatility. Built-in priors include the SIMS, SSVS and NG prior. Post-processing functions allow for doing predictions, structurally identify the model with short-run or sign-restrictions and compute impulse response function, historical decompositions and forecast error variance decompositions. Plotting functions are also available.
BGVAR is available on CRAN. The latest development version can be installed from GitHub.
install.packages("BGVAR")
devtools::install_github("mboeck11/BGVAR")Note that Mac OS needs gfortran binary packages to be installed. See also: https://gcc.gnu.org/wiki/GFortranBinaries.
Note that Windows OS needs the R package Rtools installed that you can compile code with Rcpp. There are some common issues which you find here: https://thecoatlessprofessor.com/programming/cpp/installing-rtools-for-compiled-code-via-rcpp/.
The core function of the package is bgvar() to estimate
Bayesian Global Vector Autoregressions with different shrinkage prior
setups. Calls can be heavily customized with respect to the
specification details of the model, the MCMC chain, hyperparameter setup
and various extra features. The output of the estimation can then be
used for a variety of tools implemented for the BGVAR
package.
Predictions are invoked with predict(), impulse
responses are computed with irf(), forecast error variance
decompositions can be called with fevd() and historical
decompositions with hd(). Furthermore, counterfactual
impulse responses are computed with irfcf() and conditional
forecasts with cond.predict().
The package comes with standard methods to ease the analysis. The
estimation output can be inspected with print(),
summary(), fitted(), coef(),
vcov() and residuals(). Default
plot() is available for most outputs. All classes features
print() methods. Various other helper functions to ease
analysis are also available.
