Abstract
This project focuses on the development of flexible Bayesian methods for modelling time series data. Specifically, we work on developing inference methodology from a Bayesian perspective, and then forecasting techniques for high dimensional time series data arising in economics and finance. For example, the vector of returns of portfolio constituents, or a vector of credit default swaps data for different nations.
Regarding the methodological issue, the focus of the project is on developing Bayesian methods specific to low-rank linear models, such as prior specification and efficient parameter estimation. Such models are expected to be well-suited to economics and finance data, as such data often possesses structure with dimension much lower than that what is actually observed. A Bayesian approach to low-rank linear modelling will enable adaptive determination of model parameters that are hard to estimate with classical methods.
