A Bayesian Dirichlet Auto-Regressive Conditional Heteroskedasticity Model for Forecasting Currency Shares

Harrison Katz, Robert E. Weiss

We analyze daily Airbnb service-fee shares across eleven settlement currencies, a compositional series that shows bursts of volatility after shocks such as the COVID-19 pandemic. S…

Bayesian Shrinkage in High-Dimensional VAR Models: A Comparative Study

Harrison Katz, Robert E. Weiss

High-dimensional vector autoregressive (VAR) models offer a versatile framework for multivariate time series analysis, yet face critical challenges from over-parameterization and u…

Sensitivity Analysis of Priors in the Bayesian Dirichlet Auto-Regressive Moving Average Model

Harrison Katz, Liz Medina, Robert E. Weiss

Prior choice can strongly influence Bayesian Dirichlet ARMA (B-DARMA) inference for compositional time-series. Using simulations with (i) correct lag order, (ii) overfitting, and (…
