Teacher responsible

Prof Konstantinos Kardaras

Availability

This course is available on the MSc in Quantitative Methods for Risk Management. This course is available with permission as an outside option to students on other programmes where regulations permit.

Pre-requisites

Probability and Mathematical Statistics I is a pre-requisite.

Course content

This course provides instruction in advanced topics in probability and mathematical statistics, mainly based on

martingale theory. It is a continuation of  Probability and Mathematical Statistics I. The following topics will in particular be covered:

  1. Conditional expectation revisited; linear regression; martingales and first examples.
  2. Concentration inequalities; dimension reduction; log-Sobolev inequalities.
  3. Martingale transforms; optional sampling theorem; convergence theorems.
  4. Sequential testing; backwards martingales; law of large numbers; de Finetti’s theorem.
  5. Markov chains; recurrence; reversibility; foundations of MCMC.
  6. Ergodic theory.
  7. Brownian motion; quadratic variation; stochastic integration.
  8. Stochastic differential equations; diffusions; filtering.
  9. Bayesian updating; Ergodic diffusions; Langevin samplers.
  10. Brownian bridge; empirical processes; Kolmogorov-Smirnov statistic.

Teaching

This course will be delivered through a combination of classes, lectures and Q&A sessions totalling a minimum of 30 hours across Winter Term. This course includes a reading week in Week 6 of Winter Term.

Formative coursework

Students will be expected to produce 9 problem sets in the WT.

Weekly problem sets that are discussed in subsequent seminars. The coursework that will be used for summative assessment will be chosen from a subset of these problems.
