To improve power, a number of studies have investigated the benefits of utilizing available genomic and biological information, however, the relative merits of different methods remain unclear. We focus on the stratified FDR control (Sun et al., 2006, Genetic Epidemiology 30:519-530) and weighted p-value method (Genovese et al., 2006, Biometrika 93:509-524). The two approaches model the prior info distinctively. Weighted p-value approach converts the available prior information to test-specific weighting factor and adjusts the p-values accordingly. In contrast, stratified FDR divides tests into several disjoint strata based on the prior information and applies the FDR control separately in each stratum. We formulate the two approaches in one framework and show the trade-off between power and robustness by theoretical, simulation, and application studies. Robustness is consequential in applications, safeguarding against potential uninformative or even misleading prior information. To demonstrate the practical relevance of these methods, I discuss two recent genome-wide association studies of Cystic Fibrosis modifier genes, in which over 500,000 genetic markers are investigated for association with lung functions in individuals with CF and the available prior is of quantitative nature (Wright et al. 2011, Nature Genetics 43:539-548), and for association with meconium ileus and the prior is of categorical nature (Sun et al. 2012, Nature Genetics 44:562-569). If time allows, I will briefly discuss additional interesting analytical challenges in these studies.

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedi` 9 Marzo - ore 14.00 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Elena Villa - Università degli Studi di Milano, Dipartimento di Matematica Title: MINKOWSKI CONTENT AND MEAN DENSITY OF RANDOM CLOSED SETS: some theoretical results and statistical applications Abstract: In this talk we deal with random closed sets in R^d with integer Hausdorff dimension n<d; a problem of interest in many real applications is the study of the so-called mean density of the involved set. Namely, given a random closed set Theta with Hausdorff dimension n, it may well happen that its "induced mean measure" mu(B):=E[H^n(\Theta\cap B] (where H^n denotes the n-dimensional Hausdorff measure) is absolutely continuous with respect to the d-dimensional Lebesgue measure; in such a case, the corresponding density is named the "mean density of Theta". We will give here an overview of some recent results both on its theoretical value and on its estimation in the non-stationary setting; to this aim a stochastic version of the Minkowski content notion will play a fundamental role. Tutti gli interessati sono invitati a partecipare. ................................................................................

Seminario Cretarola
by Sabrina Mulinacci 05 Mar '15

05 Mar '15

Cari colleghi, Giovedì 12 marzo 2015 ore 12 in aula IV Via Belle Arti 41, Bologna Alessandra Cretarola dell'Università di Perugia terrà un seminario dal titolo: “Risk-minimizing hedging strategies for unit-linked life insurance contracts under partial information” Abstract: We study the problem of hedging unit-linked life insurance contracts in incomplete markets when there are restrictions on the available information by using the local risk-minimization approach. This type of insurance contract is closely related to the financial market since benefits depend on the development of a certain stock price. Then, it makes sense to consider the combined model given by the underlying semimartingale model of financial market and the insurance portfolio. Firstly, we refer to the case of complete information on the insurance portfolio and a limitative knowledge on the financial market. More precisely, we assume that, at any time, the insurance company has access to the information about the number of policy-holders who are still alive but it has a partial information about the stock prices. We characterize the risk-minimizing hedging strategy for pure endowment contracts when the underlying price process is expressed in units of the numéraire portfolio and the mortality hazard rate is a deterministic function, and then we compute it explicitly in a Markovian jump-diffusion driven market model. Next, we consider the case where there are restrictions on the information concerning the insurance portfolio. In particular we assume that, at any time, the insurance company has a complete knowledge of the financial market and may observe the number of deaths from a specific portfolio of insured individuals but not the mortality hazard rate, which may depend on unobservable exogenous stochastic factors. We characterize the locally risk-minimizing hedging strategy for pure endowment and term insurance contracts in terms of the projection of the survival process on the information flow. Finally, we see that in a Markovian framework, this leads to a filtering problem with point process observations. The talk is based on joint works with Claudia Ceci and Katia Colaneri. Un caro saluto a tutti Sabrina Mulinacci

Politecnico di Milano - Seminario J. J. Egozcue and V. Pawlowsky-Glahn
by Laura M. Sangalli 04 Mar '15

04 Mar '15

Si avvisa che in data 31-03-2015, alle ore 11:00 precise, presso l'Aula Seminari "F. Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgerà il seguente seminario: Relatori: J. J. Egozcue, Dept. Matematica Aplicada III, U. Politecnica de Catalunya, Barcelona, Spain e V. Pawlowsky-Glahn, Dept. Informatica, Matematica Aplicada i Estadistica, U. de Girona, Spain Titolo: Understanding Bayes spaces Abstract: Bayes spaces contain equivalence classes of sigma-additive measures. Two measures are equivalent when they are proportional. These measures are represented by densities and vector space operations are defined. Probability measures and density functions are included in these spaces. When the densities are log-square-integrable, they are in a Hilbert space called B^2. Bayes spaces and associated Hilbert spaces B^2 have been developed in a theoretical way, but there is still a long way to understand the implications of the theory, as well as to develop potential applications. The talk is aimed at reviewing the theory and giving some examples of distributions for which the B^2 distance can be easily obtained. These examples show the variety of distribution supports that can be dealt with the theory. An application to grain size distribution is presented. The goal is to decide whether different populations have different mean distribution. Tutti gli interessati sono invitati a partecipare.

We consider situations in which the dependence structure varies with covariates and we introduce a Bayesian model that allows for joint estimation of the marginal and joint models. The dependence between the copula parameter and the covariates is modeled via polynomial splines. Extensions to multiple covariates are implemented via additive models. We discuss the computation algorithm required for inference and demonstrate the performance of model selection techniques on simulated and real data.

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Mercoledì 4 Marzo - ore 15.00 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Claudio Durastanti - Università di Tor Vergata Title: Spherical wavelets: an overview and some applications. Abstract: Our aim is to describe the construction of wavelets over the q-dimensional sphere featuring strong concentration properties in the spatial domain, introduced in literature as needlets by Narcowich, Petrushev, Ward (2006 a,b). We will also discuss some of their statistical applications: the study of quantitative central limit theorems for some linear and nonlinear statistics built from wavelet coefficients evaluated on spherical Poisson processes of arbitrary dimension. This purpose is attained by merging the Stein-Malliavin approach (introduced in the seminal paper by Peccati, Sanz-Solè, Taqqu and Utzet (2011)) and the properties of the needlets. We will also discuss some examples: the thresholding and the study of variance in nonparametric density estimation framework and the so-called Sobolev tests for uniformity. This is a joint work with Solesne Bourguin, Domenico Marinucci and Giovanni Peccati. Tutti gli interessati sono invitati a partecipare.

2 Seminari a Pavia: Jorge Bolanos e Tomasz Tylec
by Carbone Raffaella 25 Feb '15

25 Feb '15

Cari colleghi, vi annuncio che mercoledì 4 marzo, alle ore 14 precise, nell'aula Beltrami del Dipartimento di Matematica dell'Universita' di Pavia, vi saranno due seminari (entrambi nell'ambito del progetto FIRB 2010 "*Quantum Markov Semigroups and their empirical estimation*"), tenuti da Jorge Bolanos-Servin e Tomasz Tylec Seguono titoli e sunti. Distinti saluti, Raffaella Carbone ----------------------------------------------------------------------- Primo Seminario, ore 14:00 precise: Jorge Bolanos-Servin (Università UAM, Città del Messico) "Some spectral properties of Circulant Quantum Markov Semigroups" Abstract. Many symetries of $\mathbb Z_p$ are inherited by Circulant matrices , therefore widely used in many areas of mathematics. The class of Circulant QMS although described in a simple way provide examples to better understand more general ideas. In this talk i will review the relationship between the eigenvalues and eigenvectors of a Circulant matrix and a Circulant QMS GKSL generator. This will lead to prove that the spectral gap is strictly positive. ------------------------------------------------------------------------- Secondo Seminario, ore 15 precise: Tomasz Tylec (Istituto di Fisica Teorica, Varsavia) "Generalised probability, quantum logics and non-signalling theories" Abstract: Since 1990s some physicist working on quantum information theory become interested in the so-called no-signalling theories. These are very intuitive, in some sense minimal, models of compound systems. It seemed that such theories are more general than quantum mechanics. Unfortunately, they suffer from the lack of precise mathematical framework within its properties can be rigorously studied. Our aim was to find such framework and study the basic properties of most widely discussed example of non-signalling system. The most natural choice led us to the so called quantum logics. The idea stems from the works of Birkhoff and von Neumann and after many years of development it evolved into sophisticated theory of partially ordered sets. What is important such structures can be interpreted as models of a generalised probability. This allows rigorous review of previously obtained results about non-signalling theories. -- Raffaella Carbone, PhD Ricercatore di Probabilità e Statistica Matematica Dipartimento di Matematica dell'Università degli Studi di Pavia

corso di dottorato di Fabio Toninelli a Roma Tre
by Pietro Caputo 20 Feb '15

20 Feb '15

Il prof. Fabio Toninelli (Univ. Lyon 1, France) terra' un corso di dottorato di 12 ore circa presso il dipartimento di Matematica e Fisica di Roma Tre. Title: Dimer models: thermodynamics, fluctuations and Glauber dynamics Dates: March 9, 11, 16, 18, 23, 25, 30 and April 1st, 2015 Time:11.00-12.45 Location: Room 311 (third floor, palazzina C) Dipartimento di Matematica e Fisica, Roma Tre, L.go Murialdo 1 - 00146 Roma Course description: We will discuss several aspects of the mathematical theory of models of lattice dimers. These classical, two- dimensional statistical mechanics models are in certain sense “exactly solvable” (Kasteleyn, 1961). Recently there is a revival of interest in dimer models among probabilists and mathematical physiciscs, due to their properties of conformal invariance and of “Gaussian Free Field”-type fluctuations. Another aspect of great interest (in probability and theoretical computer science) is the study of the associated Markov dynamics (Glauber dynamics). In particular, a natural question concerns the speed of convergence of the dynamics to its invariant measure. Contents: – Kasteleyn theory (computation of the partition function) – dimer-dimer correlations, determinantal representation – dimer models as “lattice free fermions” – height function and its convergence to the “Gaussian Free Field” – thermodynamic limit: translation-invariant Gibbs states and limit shape – Glauber dynamics for dimer models. Connection with the zero-temperature – The problem of the speed of convergence

Conferma Seminario Prof. L. Goldstein a RM1

*Si conferma l'orario del seminario indicato qui di seguito* Grazie per l'attenzione Fabio Spizzichino =========== *V**enerdì 20 febbraio 2015* Ore 14:00, Aula di Consiglio Seminario di Probabilità Larry Goldstein (University of Southern California) *Normal approximation for recovery of structured unknowns in high dimension: Steining the Steiner formula* Intrinsic volumes of convex sets are natural geometric quantities that also play important roles in applications. In particular, the discrete probability distribution L(VC) given by the sequence v{0},...,v{d} of conic intrinsic volumes of a closed convex cone C in Rd summarizes key information about the success of convex programs used to solve for sparse vectors, and other structured unknowns such as low rank matrices, in high dimensional regularized inverse problems. The concentration of VC implies the existence of phase transitions for the probability of recovery of the unknown in the number of observations. Additional information about the probability of recovery success is provided by a normal approximation for VC. Such central limit theorems can be shown by first considering the squared length GC of the projection of a Gaussian vector on the cone C. Applying a second order Poincar´e inequality, proved using Stein’s method, then produces a non-asymptotic total variation bound to the normal for L(GC). A conic version of the classical Steiner formula in convex geometry translates finite sample bounds and a normal limit for GC to that for VC. Joint with Ivan Nourdin and Giovanni Peccati
