Inducing sparsity and shrinkage in time-varying parameter models
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 …

[HTML][HTML] Sparse Bayesian time-varying covariance estimation in many dimensions
G Kastner - Journal of Econometrics, 2019 - Elsevier
We address the curse of dimensionality in dynamic covariance estimation by modeling the
underlying co-volatility dynamics of a time series vector through latent time-varying …

Dynamic shrinkage processes
We propose a novel class of dynamic shrinkage processes for Bayesian time series and
regression analysis. Building on a global–local framework of prior construction, in which …

Sparse Bayesian vector autoregressions in huge dimensions
We develop a Bayesian vector autoregressive (VAR) model with multivariate stochastic
volatility that is capable of handling vast dimensional information sets. Three features are …

Inference in Bayesian additive vector autoregressive tree models
Vector autoregressive (VAR) models assume linearity between the endogenous variables
and their lags. This assumption might be overly restrictive and could have a deleterious …
