Availability
This course is available on the MPhil/PhD in Statistics. This course is available with permission as an outside option to students on other programmes where regulations permit. This course uses controlled access as part of the course selection process.
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:
- Conditional expectation revisited; linear regression; martingales and first examples.
- Concentration inequalities; dimension reduction; log-Sobolev inequalities.
- Martingale transforms; optional sampling theorem; convergence theorems.
- Sequential testing; backwards martingales; law of large numbers; de Finetti’s theorem.
- Markov chains; recurrence; reversibility; foundations of MCMC.
- Ergodic theory.
- Brownian motion; quadratic variation; stochastic integration.
- Stochastic differential equations; diffusions; filtering.
- Bayesian updating; Ergodic diffusions; Langevin samplers.
- Brownian bridge; empirical processes; Kolmogorov-Smirnov statistic.
Teaching
10 hours of seminars and 20 hours of lectures in the Winter Term.
This course has a reading week in Week 6 of Winter Term.
Formative assessment
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.
