Seminario di Ilaria Peri presso Prometeia - Bologna
by Giacomo Scandolo 06 Feb '15

06 Feb '15

Il giorno Giovedì 12 Febbraio 2015, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Ilaria PERI (ESC Rennes School of Business) terrà un seminario dal titolo "Lambda value at risk: a new backtestable alternative to VaR" Abstract A new risk measure, the lambda value at risk (ΛVaR), has been recently proposed from a theoretical point of view as an immediate generalization of the value at risk (VaR). The ΛVaR appears to be attractive for its potential ability to solve several problems of the VaR. This paper presents the first empirical application of the ΛVaR to equity markets. Our benchmark approach reveals that the ΛVaR is able to capture extreme downward scenarios and react to market fluctuations significantly faster than the VaR and expected shortfall. In addition, we show that the ΛVaR satisfies the elicitability property under general conditions. This property guarantees proper backtesting and statistically meaningful comparisons among ΛVaR and VaR. Hence, we perform a backtesting exercise by adapting the VaR hypothesis-testing framework. The results display a higher level of accuracy for our ΛVaR calibrations. Our comparative analysis also shows that ΛVaR performs better than VaR.

[random] PhD position in Poitiers (France) in probability/statistics, application for scholarship before 31 March 2015
by Pierre-Yves Louis 04 Feb '15

04 Feb '15

Dear Colleagues, Please forward this announcement to interested master students and potential candidates. ========================================================== PhD POSITIONS are available at the Laboratoire de Mathématiques et Applications, UMR 7348 University of Poitiers and CNRS (France) http://www.univ-poitiers.fr/home-750171.kjsp?RH=1328179805685&RF=1328179651… http://rech-math.sp2mi.univ-poitiers.fr/en/index.shtml Applications for PhD candidates in applied probability and statistics are welcome. There is a possibility to work under the supervision of Pierre-Yves LOUIS http://pylouis.perso.math.cnrs.fr/ around the topic: Stochastic dynamics for large networks Stochastic models are nowadays of main interest in several applicative fields: ecology, population biology, wildfire, social networks. More individual specificities of constituting entities (sites) can be considered. A global macroscopic state emerges from the sites’ interaction. These individually-based models are following the micro/macro description workflow defining the statistical mechanics scientific field. A large, possibly infinite, number of sites is considered. These interacting dynamical systems motivate theoretical, numerical and applied challenges. These systems of stochastic processes may be used also to sample from random fields on complicated structures as the one considered in biology. Monte-Carlo methods are used to solve related statistical questions. The PhD thesis will consider one of the following topics which are strongly related to complex systems in computer science, statistical physics and computational biology. The PhD candidate has the opportunity to choose between the following challenging projects: - Interacting Stochastic Dynamics on trees - Stochastic algorithms, Gibbs sampling - Application of stochastic methods to data classification ======================== Application deadline: 31 March 2015 through http://s2i.ed.univ-poitiers.fr/dv_demarrer_une_these/recrutement-demarrer-u… AND please contact Pierre-Yves Louis as soon as possible Please send one pdf with your resume, and possibly a list of taken courses with grades, a copy of your master thesis and at least two names as references to pierre-yves.louis(a)math.cnrs.fr ======================== For more details please see the pdf-file http://pylouis.perso.math.cnrs.fr/proposition_sujet_these_2015_LOUIS_fr.pdf and for the application procedure to http://s2i.ed.univ-poitiers.fr/dv_demarrer_une_these/recrutement-demarrer-u… ======================== Requirements You have an MSc in mathematics, with a proven interest in probability theory and statistics. Candidates with background in computational physics, computer science, mathematical biology, computational biology may be considered. ======================== Conditions of employment You will be appointed for a period of 3 years through a PhD scholarship starting 1. September 2015 minimal income : 1684,93 EUR gross/month ======================== For more information and applications please contact pierre-yves.louis(a)math.cnrs.fr Best regards, Pierre-Yves LOUIS. pierre-yves.louis(a)math.cnrs.fr http://pylouis.perso.math.cnrs.fr/

StaTalk on Biostatistics - second announcement
by Francesca Ieva 03 Feb '15

03 Feb '15

Dear all, we would like to remind you about the first StaTalk promoted by the young section of Italian Statistical Society (y-SIS), to be held in Milan (Italy) on April 24th, 2015. *STATALK ON BIOSTATISTICS* (https://sites.google.com/site/youngsocietaitalianastatistica/events/statalk…) Department of Mathematics "F. Enriques", Università degli Studi di Milano, via Saldini 50, Milano (Italy) All the information, including the program and the sign-up link for the conference, can be found on the conference website. Statalks are a series of one-day workshop aimed at early career statisticians, i.e., master degree students, people carrying out a PhD, post-docs and young researchers. StaTalks are a fantastic opportunity to share knowledge on advanced topics of statistics. The hosting research group will propose tutorials, seminars and interactive round tables on the main fields of research and application it is concerned. Participants can contribute bringing their own experience through presentations, ideas, poster and material to be shared in the debate. Registrations to the first StaTalk are opened.*No conference fees are due, but registration is mandatory, by March 30th*, using the form available on the website. For further information or any doubt and question, please visit the website https://sites.google.com/site/youngsocietaitalianastatistica/home and do not hesitate to contact me. Best Regards Francesca Ieva -- Francesca Ieva Department of Mathematics Università degli Studi di Milano, via Saldini 50, 20133 Milano web: https://sites.google.com/site/mypagefi mail to: francesca.ieva(a)unimi.it

Seminario di Probabilita' - Universita' di Padova
by alessandra bianchi 03 Feb '15

03 Feb '15

Ho il piacere di invitarvi ai seguenti seminari, che si terranno giovedì 12 Febbraio, dalle ore 14:30, nell'aula 2BC30 della Torre Archimede presso il Dipartimento di Matematica dell'Universita' degli Studi di Padova. 14.30 -15.30 Giuseppe Canizzaro (Technical University of Berlin) TITLE: SDEs with distributional drift and Polymer measure ABSTRACT: We study existence and uniqueness of solution for stochastic differential equations with distributional drift by giving a meaning to the Strook-Varadhan martingale problem associated to such equations. The approach we exploit is the one of paracontrolled distributions recently introduced by Gubinelli, Imkeller and Perkowski in their by now celebrated paper "paracontrolled distributions and singular PDEs". As a result, we make sense of the two and three dimensional polymer measure and show some of its properties. 15.30-16.30 Alberto Chiarini (Technical University of Berlin) TITLE: (Local) CLT for symmetric Diffusions in a degenerate Random Environment. ABSTRACT: We study a symmetric diffusion $X$ on $\mathbb{R}^d$ in divergence form in a stationary and ergodic environment, with measurable unbounded and degenerate coefficients. The diffusion is formally associated with $L^\omega u = \nabla\cdot(a^\omega\nabla u)$. We prove for $X$ a quenched (local) central limit theorem, under some moment conditions on the environment; the key tools are the sublinearity of the corrector and a parabolic Harnack's inequality both obtained using the celebrated Moser's iteration technique. -- Alessandra Bianchi Dip. di Matematica Pura e Applicata Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/
