# Fast and Flexible Bayesian Inference in Time-varying Parameter Regression Models

@article{Hauzenberger2021FastAF, title={Fast and Flexible Bayesian Inference in Time-varying Parameter Regression Models}, author={Niko Hauzenberger and Florian Huber and Gary Koop and Luca Onorante}, journal={Journal of Business \& Economic Statistics}, year={2021} }

In this paper, we write the time-varying parameter regression model involving K explanatory variables and T observations as a constant coefficient regression model with TK explanatory variables. In contrast with much of the existing literature which assumes coefficients to evolve according to a random walk, this specification does not restrict the form that the time-variation in coefficients can take. We develop computationally efficient Bayesian econometric methods based on the singular value…

Bayesian Inference in High-Dimensional Time-varying Parameter Models using Integrated Rotated Gaussian Approximations

- Computer Science, Mathematics
- 2020

This paper develops computationally efficient Bayesian methods for estimating TVP models using an integrated rotated Gaussian approximation (IRGA), exploiting the fact that whereas constant coefficients on regressors are often important, most of the TVPs are often unimportant.

General Bayesian time-varying parameter VARs for predicting government bond yields

- Economics
- 2021

Time-varying parameter (TVP) regressions commonly assume that timevariation in the coefficients is determined by a simple stochastic process such as a random walk. While such models are capable of…

Dynamic Shrinkage Priors for Large Time-varying Parameter Regressions using Scalable Markov Chain Monte Carlo Methods

- Computer Science, Mathematics
- 2020

A new dynamic shrinkage prior is proposed which reflects the empirical regularity that TVPs are typically sparse and is found to effectively pick out small amounts of parameter change and the methods to forecast well.

Sparse time-varying parameter VECMs with an application to modeling electricity prices

- Economics, Computer Science
- 2020

This paper combines a set of econometric techniques for dynamic model specification in an automatic fashion and employs continuous global-local shrinkage priors for pushing the parameter space towards sparsity, alleviating overfitting concerns and reduces parameter estimation uncertainty.

Flexible Mixture Priors for Time-varying Parameter Models

- Mathematics
- 2020

Time-varying parameter (TVP) models often assume that the TVPs evolve according to a random walk. This assumption, however, might be questionable since it implies that coefficients change smoothly…

A forecasting procedure based on a Bayesian method for estimating vector autoregressions is applied to ten macroeconomic variables and is shown to improve out-of-sample forecasts relative to univariate equations.

Inducing Sparsity and Shrinkage in Time-Varying Parameter Models

- EconomicsJournal of Business & Economic Statistics
- 2020

Abstract Time-varying parameter (TVP) models have the potential to be over-parameterized, particularly when the number of variables in the model is large. Global-local priors are increasingly used to…
