    Time: 12.00 noon Abstract:  XTX Markets trades an average of $80B daily in thousands of financial instruments  on an electronic basis with  little human interaction. This adds liquidity to the global financial markets and is made possible by taking a highly systematic, purely data-driven, approach to trading.  In this talk, we will describe how trading can be automated, the sort of problems that it poses, and how a small team of mathematicians, ...

    Speaker: Geoff Nicholls, Department of Statistics, University of Oxford Title: The Savage Axioms for Dummies Abstract: In Bayesian inference the subjective expected utility is an object of foundational importance. The decision maker’s choices maximise this utility, and so it decides some elements of our statistical methodology. For the SEU to exist we need a prior and a utility representing the subjective beliefs of the analyst to exist. The Savage Axioms are a...

    Speakers: Professor Charlotte Deane and Professor Gesine Reinert, Department of Statistics, University of Oxford Title: Active and Passive Presentations: how to present your work, and how to get the most out of seminars, lectures and poster sessions. Time and Place: 3.30pm, Small Lecture Theatre

    Speaker: Raphael Forien, CMAP – École Polytechnique, France Title: Gene flow across geographical barriers Abstract: Barriers to gene flow are physical or biological obstacles which locally reduce migration and genetic exchanges between different regions of a species’ habitat. Genetic relatedness between individuals can be deduced from the distribution of the positions of their ancestors back in time. In the prese...

    Speaker: Professor Peter Hoff, Department of Statistics, Duke University Title: Adaptive FAB confidence intervals with constant coverage Abstract: Confidence intervals for the means of multiple normal populations are often based on a hierarchical normal model. While commonly used interval procedures based on such a model have the nominal coverage rate on average across a population of groups, their actual coverage rate for a ...

    Speaker: David Swafford, Senior Research Scientist, Biological Sciences, Duke University Title: Generality and Robustness of the SVDQuartets Method for Phylogenetic Species Tree Estimation Abstract: Methods for inferring evolutionary trees based on phylogenetic invariants were first proposed nearly three decades ago, but have been virtually ignored by biologists. A new invariants-based method for estimating species trees unde...

    Speaker: Mikolaj Kasprzak, Department of Statistics, University of Oxford Title: Diffusion approximations via Stein’s method and time changes Abstract: We extend the ideas of (Barbour, 1990) and use Stein’s method to obtain a bound on the distance between a scaled time-changed random walk and a time-changed Brownian Motion. We then apply this result to bound the distance between a time-changed compensated scaled Poi...
