PhD Studentship in Bayesian computation

Supervisor: Dr. Wentao Li

Start date: September 2023

A fully funded PhD studentship is available in the Department of Mathematics of the University of Manchester, UK.

The studentship covers tuition fees and standard UK PhD stipend for 3.5 years, but is available only to students eligible for home fees (typically, applicants from the UK).

Closing date for applications: 28nd December, 2022

Simulation-based inference for financial econometrics models

In modern statistical applications,  many complicated models have two common features. First the likelihood functions are often difficult to evaluate;  second the model is generative. In particular,  financial time series data pose the following challenges. First, when latent stochastic dynamics are considered, e.g. volatilities and regime switching, the likelihood is intractable. Second, in the big data era, the more sophisticated model is required for high-frequency data and their microstructure. The class of simulation-based methods is often used for statistical inference of intractable likelihood models by using model simulations. The inference is usually conducted under the Bayesian framework, providing uncertainty quantifications for both parameter estimation and prediction. It has seen successful applications and become increasingly popular in a wide range of areas, including population genetics, ecology, astronomy, etc. This project aims to develop new simulation-based statistical computing algorithms with emphasis on financial econometrics models. The underpinning convergence theory will be developed. Building blocks of the new algorithms include approximate Bayesian computation, sequential Monte Carlo, Markov chain Monte Carlo, Bayesian synthetic likelihood, their synergies, etc.
