Seminario Prof. Jorge P. Zubelli
by Sabrina Mulinacci 13 Sep '15

13 Sep '15

Carissimi tutti, segnalo il seguente seminario del Prof. Jorge P. Zubelli, dell'IMPA di Rio de Janeiro che si terrà in Aula 1 presso il Dipartimento di Scienze Statistiche “P. Fortunati” in Via Belle Arti 41, 40126 Bologna. Tutti gli interessati sono invitati a partecipare Un caro saluto Sabrina Mulinacci ********************************************************************* Prof. Jorge P. Zubelli, dell'IMPA di Rio de Janeiro Titolo del seminario: "Calibration of Local Volatility Models from Option Data for Commodities." Abstract: Local volatility models are extensively used and well-recognized for hedging and pricing in financial markets. They are frequently used, for instance, in the evaluation of exotic options so as to avoid arbitrage opportunities with respect to other instruments. Derivatives for commodities are extensively traded instruments in financial markets, especially in energy and oil ones. They are particularly challenging since the spot prices are not directly observable, thus requiring a further modeling effort. The ill-posed character of local volatility surface calibration from market prices requires the use of regularization techniques either implicitly or explicitly. Such regularization techniques have been widely studied for a while and are still a topic of intense research. We have employed convex regularization tools and recent inverse problem advances to deal with the local volatility calibration problem. In this talk we shall describe ongoing work on the use local volatility models in the context of commodity markets, in particular applied to energy and oil ones. This work is part of ongoing collaboration with V. Albani (Vienna), U. Ascher (Toronto), and Xu Yang (IMPA).

seminario Patrick Beissner
by Emanuela Rosazza 11 Sep '15

11 Sep '15

Cari tutti, martedì 15 settembre alle ore 16 il Dott. Patrick Beissner (Bielefeld University, Germania) terrà in Bicocca (edificio U7- aula 2062 (aula demografica) – secondo piano) un seminario dal titolo “Asset Pricing and Bubbles under Sentiment-Based Expectations”. Abstract: We propose a formal theory of asset pricing that allows us to explain how sentiments in the market may influence price formation. A fully nonlinear expectation captures behavioral market sentiments in terms of waves between optimism and pessimism. The approach follows the standard procedure by extracting some stochastic Euler equation from a representative agent equilibrium model. Preferences are represented through sentiment-based expected utility. In equilibrium, the resulting asset price process can then be described by a new (nonlinear) conditional sentiment-based expectation. In a final step, we observe the possible emergence of a bubble that is induced by disagreement of optimism and pessimism for the market relevant pricing measures. Joint work with Patrick Cheridito. Tutti gli interessati sono invitati a partecipare. Un saluto e a presto, Emanuela ******************************************************************************************* Emanuela Rosazza Gianin Dipartimento di Statistica e Metodi Quantitativi Università di Milano-Bicocca Edificio U7 – 4° Piano Via Bicocca degli Arcimboldi, 8 20126 Milano Tel. 02 64483208 Fax. 02 64483105 e-mail: emanuela.rosazza1(a)unimib.it *******************************************************************************************

Gentilissimi/e, vi invio un avviso di seminario, con preghiera di massima diffusione. Sede del seminario: Istituti Biologici 2, Università di Verona, strada Le Grazie 8 (VERONA). Distinti saluti, Alessandro Marcon Alessandro Marcon, PhD Unit of Epidemiology & Medical Statistics Department of Diagnostics and Public Health University of Verona Strada Le Grazie 8, 37134 Verona, Italy tel. +39 045 8027668 Avviso di SEMINARIO Lunedì 12 ottobre 2015 ore 11.00-11.45 Aula Igiene & Statistica (Istituti Biologici 2, blocco B, secondo piano) Dr. Cosetta Minelli Senior Lecturer in Medical Statistics, National Heart and Lung Institute, Imperial College London *Mendelian randomization: * *The use of genes as instruments to strengthen causal inference in epidemiology* Mendelian randomization is an approach that uses genes as instrumental variables to derive unconfounded estimates of the effects of risk factors (e.g. biomarkers) on disease traits, and is therefore increasingly being used in epidemiology to distinguish causal from spurious associations. Since genes are randomly allocated at conception, genetic effects on a biomarker cannot be affected by classical confounding (e.g. lifestyle factors) or reverse causation (e.g. biomarker level being influenced by the presence of disease). Demonstration that a genetic variant known to modify the biomarker also modifies the disease trait represents indirect evidence of a causal biomarker-disease association. The validity of Mendelian Randomization, however, is based on instrumental variable assumptions, the most important being absence of pleiotropy. This talk will describe the approach, discuss ways to assess pleiotropy, highlight opportunities and challenges offered by available genome-wide data, and discuss its extension to the field of epigenetics (two-step epigenetic Mendelian randomization).

de Finetti Risk seminar - september 2015
by Emanuela Rosazza 08 Sep '15

08 Sep '15

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Title: Project Evaluation under Uncertainty: From Minimal Martingale Measures to Implementation. Speaker: Jorge P. Zubelli (IMPA) Abstract: Industrial strategic decisions have evolved tremendously in the last decades towards a higher degree of quantitative analysis. Such decisions require taking into account a large number of uncertain variables and volatile scenarios, much like financial market investments. Furthermore, they can be evaluated by comparing to portfolios of investments in financial assets such as in stocks, derivatives and commodity futures. This revolution led to the development of a new field of managerial science known as Real Options. The use of Real Option techniques incorporates also the value of flexibility and gives a broader view of many business decisions that brings in techniques from quantitative finance and risk management. Such techniques are now part of the decision making process of many corporations and require a substantial amount of mathematical background. Yet, there has been substantial debate concerning the use of risk neutral pricing and hedging arguments to the context of project evaluation. We discuss some alternatives to risk neutral pricing that could be suitable to evaluation of projects in a realistic context with special attention to projects dependent on commodities and non-hedgeable uncertainties. More precisely, we make use of a variant of the hedged Monte-Carlo method of Potters, Bouchaud and Sestovic to tackle strategic decisions. This leads to interesting numerical analysis questions and to connections with BSDEs. LOCATION: The seminar will be held on Thursday, September 17, at 18.00, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano. A refreshment will be offered at 17.30. Take note that de Finetti Risk Seminars will be held on Thursday only for this talk, while they are usually planned on Wednesday.

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Mercoledi 9 Settembre 2015 alle ore 12:30, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Mingyuan ZHOU (University of Texas at Austin) THE POISSON GAMMA BELIEF NETWORK Abstract: A key issue in deep learning is to define an appropriate network structure, including both the depth of the network and the width of each hidden layer, which may be naturally addressed with completely random measures. We propose the Poisson gamma belief network (PGBN), which factorizes each of its layers into the product of a connection weight matrix and the nonnegative real hidden units of the next layer, to infer a multilayer representation of high-dimensional count vectors. We use the gamma-negative binomial process together with a layer-wise training strategy to infer the network structure, allowing the width of each hidden layer to grow without bound. We further demonstrate that with a fixed budget on the width of the first layer, the PGBN can increase its number of hidden layers to boost its performance. We propose an efficient upward-downward Gibbs sampler to jointly train all the hidden layers of the PGBN, with example results on text analysis illustrating its efficacy and unique properties. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.
