Bayesian model comparison for time‐varying parameter VARs with stochastic volatility

JCC Chan, E Eisenstat - Journal of applied econometrics, 2018 - Wiley Online Library
We develop importance sampling methods for computing two popular Bayesian model
comparison criteria, namely, the marginal likelihood and the deviance information criterion …

[HTML][HTML] Achieving shrinkage in a time-varying parameter model framework

A Bitto, S Frühwirth-Schnatter - Journal of Econometrics, 2019 - Elsevier
Shrinkage for time-varying parameter (TVP) models is investigated within a Bayesian
framework, with the aim to automatically reduce time-varying parameters to static ones, if the …

[HTML][HTML] Triple the gamma—A unifying shrinkage prior for variance and variable selection in sparse state space and TVP models

A Cadonna, S Frühwirth-Schnatter, P Knaus - Econometrics, 2020 - mdpi.com
Time-varying parameter (TVP) models are very flexible in capturing gradual changes in the
effect of explanatory variables on the outcome variable. However, in particular when the …

Bayesian compressed vector autoregressions

G Koop, D Korobilis, D Pettenuzzo - Journal of Econometrics, 2019 - Elsevier
Macroeconomists are increasingly working with large Vector Autoregressions (VARs) where
the number of parameters vastly exceeds the number of observations. Existing approaches …

Forecasting in the presence of instabilities: How we know whether models predict well and how to improve them

B Rossi - Journal of Economic Literature, 2021 - aeaweb.org
This article provides guidance on how to evaluate and improve the forecasting ability of
models in the presence of instabilities, which are widespread in economic time series …

Reducing the state space dimension in a large TVP-VAR

JCC Chan, E Eisenstat, RW Strachan - Journal of Econometrics, 2020 - Elsevier
This paper proposes a new approach to estimating high dimensional time varying parameter
structural vector autoregressive models (TVP-SVARs) by taking advantage of an empirical …

Asymmetric conjugate priors for large Bayesian VARs

JCC Chan - Quantitative Economics, 2022 - Wiley Online Library
Large Bayesian VARs are now widely used in empirical macroeconomics. One popular
shrinkage prior in this setting is the natural conjugate prior as it facilitates posterior …

Parsimony inducing priors for large scale state–space models

HF Lopes, RE McCulloch, RS Tsay - Journal of Econometrics, 2022 - Elsevier
State–space models are commonly used in the engineering, economic, and statistical
literature. They are flexible and encompass many well-known statistical models, including …

Fast computation of the deviance information criterion for latent variable models

JCC Chan, AL Grant - Computational Statistics & Data Analysis, 2016 - Elsevier
The deviance information criterion (DIC) has been widely used for Bayesian model
comparison. However, recent studies have cautioned against the use of certain variants of …

Fast and accurate variational inference for large Bayesian VARs with stochastic volatility

JCC Chan, X Yu - Journal of Economic Dynamics and Control, 2022 - Elsevier
We propose a new variational approximation of the joint posterior distribution of the log-
volatility in the context of large Bayesian VARs. In contrast to existing approaches that are …
