Bayesian Estimation of the GARCH(1,1) Model with Student-t Innovations

Provides the bayesGARCH() function which performs the Bayesian estimation of the GARCH(1,1) model with Student's t innovations as described in Ardia (2008) .

Bayesian estimation of the GARCH(1,1) model with Student-t innovations

DOI CRAN Downloads Downloads

The package bayesGARCH (Ardia and Hoogerheide, 2010) implements in R the Bayesian estimation procedure described in Ardia (2008) for the GARCH(1,1) model with Student-t innovations. The approach consists of a Metropolis-Hastings (MH) algorithm where the proposal distributions are constructed from auxiliary ARMA processes on the squared observations. This methodology avoids the time-consuming and difficult task, especially for non-experts, of choosing and tuning a sampling algorithm.
