Seminario K. Colaneri - Università di Milano-Bicocca
by elena bandini 02 Oct '18

02 Oct '18

Annuncio di Seminario Speaker: Katia Colaneri (University of Leeds) Titolo: Indifference pricing of life insurance contracts in a market with longevity bounds via BSDEs under partial informations. Giovedì' 04 Ottobre 2018, ore 12:00 Dipartimento di Matematica e Applicazioni Università di Milano-Bicocca Via Cozzi 55, Milano - edificio U5 - Aula 3014 Abstract: We investigate the pricing problem of a pure endowment contract when the insurer has a limited information on the mortality intensity of the policyholder. We consider a financial market, where investments in a riskless asset, a risky asset and a longevity bond are allowed. Our modelling framework that takes into account mutual dependence between the financial and the insurance markets via an observable stochastic process, which affects the risky asset and the mortality index dynamics. Computing indifference price amounts to solve a stochastic control problem. Under partial information this methodology requires filtering techniques that can reduce the original control problem to an equivalent problem in complete information. We characterize the value function as well as the indifference price in terms of the solution to a quadratic-exponential backward stochastic differential equation. Tutti gli interessati sono invitati a partecipare. Cordialmente, Elena Bandini

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 5 Ottobre 2018, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Fernando A. QUINTANA (Pontificia Universidad Catolica de Chile) DISCOVERING INTERACTIONS USING COVARIATE INFORMED RANDOM PARTITION MODELS Combination chemotherapy treatment regimens created for patients diagnosedwith childhood acute lymphoblastic leukemia have had great success inimproving cure rates. Unfortunately, patients prescribed these types oftreatment regimens have displayed susceptibility to the onset ofosteonecrosis. Some have suggested that this is due to pharmacokineticinteraction between two agents in the treatment regimen (asparaginase anddexamethasone) and other physiological variables. Determining whichphysiological variables to consider when searching for interactions inscenarios like these, minus a priori guidance, has proved to be achallenging problem, particularly if interactions influence the responsedistribution in ways beyond shifts in expectation or dispersion only. We propose an exploratory technique that is able to discoverassociations between covariates and responses in a very general way. Theprocedure connects covariates to responses very flexibly through dependentrandom partition prior distributions, and then employs machine learningtechniques to highlight potential associations found in each cluster. Weapply the method to data produced from a study dedicated to learning whichphysiological predictors influence severity of osteonecrosis multiplicatively. ------------------------------------------------ Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

Seminario Prof. N. Leonenko - Roma
by Luisa Beghin 28 Sep '18

28 Sep '18

*Seminario congiunto Università Sapienza - Tor Vergata, Roma* *Mercoledì 3 ottobre 2018* Ore 15:00, Aula 34 (iv piano) Dipartimento di Scienze Statistiche, Sapienza *Titolo: *Limit theorems, scaling of moments and intermittency for integrated finite variance supOU processes *Speaker:* Prof. N. Leonenko (Cardiff University, UK) *Abstract:* Superpositions of Ornstein-Uhlenbeck type (supOU) processes provide a rich class of stationary stochastic processes for which the marginal distribution and the dependence structure may be modeled independently. In this paper we investigate the limiting behavior of integrated supOU processes with finite variance. We show that after suitable normalization four different limiting processes may arise. The type of limit depends on the decay of the correlation function as well as on the characteristic triplet of the marginal distribution. SupOU processes, moreover, may exhibit intermittency, a phenomenon affecting the rate of growth of moments. We establish this rate for each of the four limiting scenarios. The rate changes at some point indicating that there is a change-point in the asymptotic behavior of absolute moments. For such a behavior to be possible, the moments in the limit theorem do not converge beyond some critical point. We show that this point is related to the dependence structure of the supOU process. The intermittency phenomenon appears also in some other models, for example, Intermittency of trawl processes. Joint work with D. Grahovac (Osijek University, Croatia) and M. Taqqu (Boston University, USA). Tutti gli interessati sono invitati ad intervenire. Cordiali saluti.

Annuncio di seminario a Roma La Sapienza
by Faggionato, Alessandra 27 Sep '18

27 Sep '18

Martedi` 2 Ottobre, ore 14.00 Aula di Consiglio, Dipartimento di Matematica, La Sapienza Speaker: F. Patras (University of Nice) Title: Revisiting chaos expansions and Wick products Abstract: Recently, the interest in the structure of cumulants and Wick products for non-Gaussian variables has been revived, since they both play important roles in M. Hairer’s theory of regularity structures. We present a new approach to the theory based on tools (group actions, Hopf algebras) that allow to understand the theory of Wick products as a deformation, a presentation from which many of their properties follow easily. We also discuss how these ideas appear in the theory of regularity structures. Based on j.w. with K. Ebrahimi-Fard, N. Tapia, L. Zambotti.

Seminario F. Caravenna - Univ. Bocconi, Milano
by Antonio Lijoi 24 Sep '18

24 Sep '18

DEC-Statistics Seminar @ Bocconi University, Milano Thursday, September 27 12:30 Meeting room 3-e4-sr03, Via Roentgen 1, 3rd floor Francesco Caravenna (Universita' degli studi di Milano - Bicocca) Title: Local large deviations and the strong renewal theorem Abstract: We present two different, but related results for random walks with heavy tails (more precisely: in the domain of attraction of a stable law with infinite mean). The first result is a local large deviation upper bound, which improves on the classical local central limit theorem. The second result is the derivation of necessary and sufficient conditions for the so-called strong renewal theorem, which is the analogue of Blackwell's renewal theorem in the case of infinite mean. This solves a long standing problem, which dates back to a classical paper by Garsia and Lamperti (Comment. Math. Helv. 1962). (Based on joint work with Ron Doney) The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar ---------- Please note: If you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it In addition, we suggest to print, fill out and send the attached form (to give your consent to personal data handling) via email to the same address. In this way, the check-in procedure at the entrance will be faster and easier.

Seminario di Lorenzo Taggi a Roma Tre il 3/10/18 h16
by Pietro Caputo 24 Sep '18

24 Sep '18

Annuncio di Seminario Speaker: Lorenzo Taggi (TU Darmstadt, Germania) Titolo: Conservative interacting particle systems: "Oil and Water" and "Activated Random Walk". Mercoledi' 03 Ottobre 2018 ORE 16:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract We consider two interacting particle systems, Activated Random Walk (ARW) and Oil and Water (OW). One of the main features of these systems is that the number of particles is conserved: This conservation law introduces hard-core constraints and long-range correlations which make the mathematical analysis particularly challenging. In this talk the main questions and results concerning these models are presented: In ARW, if the particle density is small enough, the activity dies out with time, while if the particle density is large enough the activity is sustained; moreover a non-trivial characterization of the critical density is available. Contrary to ARW, no phase transition occurs in OW: The activity dies out with time does not matter how large the particle density is. Based on joint works with E. Candellero and A. Stauffer.
