The BVAR R package helps analyze complex data patterns in economics and finance using Bayesian Vector Autoregression models. By setting informative priors, the package structures model coefficients for better predictions. BVAR offers tools for exploring impulse responses, making forecasts, and customizing priors. This user-friendly package simplifies the estimation of Bayesian VAR models with hierarchical prior selection, making it easier for researchers to analyze multivariate time series data.
