Dynamic Factor Stochastic Volatility-in-Mean VAR for Large Macroeconomic Panels

Daichi Hiraki, Siddhartha Chib, Yasuhiro Omori

We develop a dynamic factor stochastic volatility-in-mean (SVM) specification for vector autoregressions (VARs) that embeds an SVM component within a dynamic factor stochastic vola…

Unified Mixture Sampler for State-Space Models: Application to Stochastic Conditional Duration Models

Daichi Hiraki, Yasuhiro Omori

We propose a unified mixture sampler (UMS) that provides a universal estimation framework for nonlinear state-space models with "exp-exp" likelihood kernels. Unlike existing method…

Realized Stochastic Volatility Model with Skew-t Distributions for Improved Volatility and Quantile Forecasting

Makoto Takahashi, Yuta Yamauchi, Toshiaki Watanabe +1

Accurate forecasting of volatility and return quantiles is essential for evaluating financial tail risks such as value-at-risk and expected shortfall. This study proposes an extens…
