Although these methods have been and are highly successful in making likelihood-based inference accessible to a wide range of problems from almost every area of science and technology, they have their limitations. For example, in high-dimensional problems and for massive data sets. Thus many challenging statistical inference problems of the 21st century cannot be addressed using standard likelihood-based methods. Examples which motivate the workshop come from network data, disease epidemiology, medical imaging, ecology, cell biology, climate extremes and airport design.
There have been various recent breakthroughs in computational and statistical approaches to intractable likelihood problems. These include likelihood-free methods such as Approximate Bayesian Computation (ABC), composite and pseudo likelihoods, synthetic and indirect likelihoods, new simulation methods for hitherto intractable stochastic models, and adaptive Monte Carlo methods.
Presenters and tutors include:
- Professor Nial Friel, University College Dublin
- Dr Riccardo Rastelli, University College Dublin
- Professor Tony Pettitt, QUT and Chief Investigator at ACEMS
