Cointegration analysis has been influenced by the non-linearity so that cointegration models that allow regime switching or structural breaks have been analysed by many econometricians. Unfortunately, these nonlinear cointegration models tend to be complicated both in terms of estimation and testing. In this paper, a fully parametric Bayesian estimator, robust to nonstationarity, is designed for the fractionally integrated, autoregressive, stochastic volatility (SV-FIAR) model. Joint estimates of the autoregressive and fractional differencing parameters of volatility are found via a Bayesian, Markov chain Monte Carlo (MCMC) sampler.

Keywords: Interest rate swaps, swap spreads, term structure of interest rates, regime switching, Description Implements nonlinear autoregressive (AR) time series models. For univariate se-ries, a non-parametric approach is available through additive nonlinear AR. Parametric model-ing and testing for regime switching dynamics is available when the transition is either di-rect (TAR: threshold AR) or smooth (STAR: smooth transition AR, LSTAR). 1 The Bayesian Paradigm. The ideas behind the Bayesian approach differ fundamentally from the classical inference (or the frequentist approach). Broadly speaking, when making use of classical inference we condition on the existence of a parameter vector, say \(\Theta\), that governs the data generating process (DGP) from which the observed sample of data is thought to have been obtained. We develop a regime-switching SVAR (structural vector autoregression) in which the monetary policy regime, chosen by the central bank responding to economic condi-tions, is endogenous and observable.

Class participation is strongly encouraged and will be taken into Threshold Vector Autoregression (TVAR) models and Markov-switching Vector Autoregression (MS-VAR) models. MS-VAR models define different regimes by changes in the parameters that capture the transmission of shocks and their variances.4 The structural changes in TVAR models take place when a prespecified transition variable exceeds an models, Bayesian vector autoregression models, count time series, Markov-switching and change-point models, and forecast evaluation. This course is intended for those who have taken the four-week workshop on Time Series Mar 15, 2014 · Regime Switching Model with Endogenous Autoregressive Latent Factor∗ Yoosoon Chang† Yongok Choi‡ Joon Y. Park§ Abstract This paper introduces a model with regime switching, which is driven by an autoregressive latent factor correlated with the innovation to the observed time series. In our model, the mean or volatility process is ... Markov-Switching vector autogressive model (MS-VAR) Posted 08-02-2013 05:49 AM (2114 views) Does anybody know the SAS code for the Markov regime switching autoregressive model by Sims and Zha (2006) ? TIME VARYING STRUCTURAL VECTOR AUTOREGRESSIONS: A CORRIGENDUM 4 steps remain the same, they can all be implemented as in Primiceri (2005).1 Algorithm 2 is therefore equivalent to switching steps (d) and (e) in the algorithm summarized in Appendix A.5 of Primiceri
