 Description: Assists in the set-up of algorithms for Bayesian inference of vector autoregressive (VAR) and error correction (VEC) models. Functions for posterior simulation, forecasting, impulse response analysis and forecast error variance decomposition are largely based on the introductory texts of Chan, Koop, Poirier and Tobias (2019, ISBN: 9781108437493), Koop and Korobilis (2010) <doi:10.1561/0800000013> and Luetkepohl (2006, ISBN: 9783540262398).

 # bvartools 0.2.4
 
+* Dropped some error messages to fix a security concern with `Rcpp::stop`.
 * `stochvol_ocsn2007` can handle multi-column input.
 * `stochvol_ksc1998` can handle multi-column input.
 * Added `post_gamma_state_variance` for posterior simulation of constant error variances of the state equation.
