Seminario MATECHOU
by Matteo Ruggiero 16 Nov '18

16 Nov '18

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 23 Novembre 2018, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Eleni MATECHOU (University of Kent) BAYESIAN NONPARAMETRIC MODELLING OF PHENOLOGY USING CAPTURE-RECAPTURE DATA. Phenological shifts, that is changes in the timing of cyclic and seasonal phenomena, have been observed for a number of wildlife species in recent years. These shifts are often attributed to the warming climate and their effect on population sizes is a matter of great concern. In this talk, I show how Bayesian nonparametrics can be employed when modelling capture-recapture data to obtain smooth and ecologically meaningful estimates of arrival and departure densities at one or more sites and as functions of environmental covariates or to account for individual phenological heterogeneity. ------------------------------------------------ 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. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

15 Nov '18

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Mathias Beiglboeck University of Vienna Title: Adapted transport and mathematical finance Abstract: Adapted transport plans generalize adapted processes in the same way as usual transport plans are a relaxed form of Monge-mappings. Correspondingly, one obtains an adapted / causal variant of the usual Wasserstein distance. We will review these concepts and explain why they are relevant for mathematical finance and in particular the problems involving model-uncertainty. LOCATION: The seminar will be held on Wednesday, November 21, at 18.00, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano.

Si avvisa che in data 21-11-2018, alle ore 14:30 precise, presso l'Aula Seminari "F. Saleri" VI piano, Dipartimento di Matematica, Politecnico di Milano, si svolgerà il seguente seminario: Relatore Eva Fiserova, Palacky University Olomouc, Czech Republic Titolo Working with compositional data in coordinates Abstract Compositional data are multivariate observations carrying only relative information, popularly expressed in percentages, proportions, mg/kg, etc. Because of features inherent to compositional data, such as scale invariance and the relative scale, the statistical analysis of raw compositional data often leads to spurious results. Natural principles of compositional data are followed by the Aitchison geometry on a simplex, the sample space of compositional data (Aitchison, 1986; Pawlowsky-Glahn et al., 2015). However, because most standard statistical methods rely on the Euclidean geometry in real space, compositional data need to be converted to this space prior to statistical processing. In the lecture, we will present the log ratio methodology for dealing with compositional data and several types of their coordinate representations, such as orthonormal log-ratio coordinates, pivot coordinates, weighted pivot coordinates (Hron et al., 2017), or symmetric balances (Kynvclova et al., 2017). Their usage will be demonstrated on examples. Tutti gli interessati sono invitati a partecipare.

In its most basic form, (external) regret minimization guarantees that an agent’s cumulative payoff is no worse in the long run than that of the agent’s best fixed action in hindsight. Going beyond this worst-case guarantee, we consider a dynamic regret variant that compares the agent’s accrued rewards to those of any sequence of play. Specializing to a wide class of no-regret strategies based on mirror descent, we derive explicit rates of regret minimization relying only on imperfect gradient observations. We then leverage these results to show that players are able to stay close to Nash equilibrium in time-varying monotone games – and even converge to Nash equilibrium if the sequence of stage games admits a limit.”* The calendar of the future seminars can be found at http://economiaefinanza.luiss.it/en/seminari/prossimi-seminari ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza LUISS Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

seminario 13 novembre 9, 30 al Politecnico di Torino DISMA
by Enrico Bibbona 06 Nov '18

06 Nov '18

Martedi' 13 novembre alle 9,30 in Aula Buzano (Politecnico di Torino, DISMA) il prof Badal Joshi (California State University San Marcos) terrà un seminario dal titolo Graphical symmetries of reaction networks and their stationary measures Abstract: Reaction networks are used to model chemical reactions, biochemical reactions, interacting populations in ecology, genetics and infectious disease dynamics among many other systems. Depending on the system scale, three most commonly used models are continuous-time Markov chain (CTMC), stochastic differential equations and ordinary differential equations (ODE). With increased data and scientific focus shifting towards biochemistry which often involves populations as small as few tens of molecules, CTMC models have seen dramatic increase in relevance. The long-term dynamics of a continuous-time Markov chain model are described by its stationary distribution. In general, the explicit form of the stationary distribution is impossible to obtain even for very small networks. However, when the network has some natural symmetries, we can obtain the explicit stationary distribution and it can be connected with the equilibria of the corresponding ODE system. We will discuss the symmetries of reaction balance, complex balance, reaction vector balance, and cycle balance and their properties in both the deterministic (ODE) setting and stochastic (CTMC) setting. We will also discuss the relations between the various forms of balance and the connection with existence and form of the stationary distribution.

seminario Felix Liebrich - 22 novembre

06 Nov '18

Si avvisa che il giorno giovedì 22 novembre alle ore 14 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Felix-Benedikt Liebrich (LMU Muenchen, Germany) Titolo: “Sharing utility and risk under (partial) law-invariance” Abstract: The so-called risk sharing problem has two variants: (1) How can an aggregation of individual utilities within a system of agents be maximised by means of distributing a certain good, or (2) how can an aggregation of individual risks be minimised by means of redistributing a certain loss the system incurs? The problem has a long history in economics and financial mathematics, and solving it in relevant infinite dimensional spaces is very challenging. Substantial results have been obtained in the context of Pareto efficiency of such sharing schemes when law-invariant (risk) preferences are involved. These rank Savage acts -- random variables -- in a way which only depends on their distribution under a fixed reference probability measure. It was shown that Pareto efficient allocations (i.e. sharing schemes) exist. For problem (1) of maximising aggregated utility, the talk presents a unifying framework in which solutions to the risk sharing problem can be found. As applications, we will discuss the existence of weakly Pareto efficient allocations, Pareto efficient allocations, and core allocations. In a second part, we solve the risk sharing problem (2) for a wide class of capital requirements determining individual risks. These will not be law-invariant functionals, but build on a law-invariant ingredient. The talk is based on joint work with Gregor Svindland. Tutti gli interessati sono invitati a partecipare.

Avviso di seminario

Avviso di Seminario Martedì 6 Novembre, ore 14:30 presso la Facoltà di Economia dell'Università di Roma "Tor Vergata" Aula A, Edificio B ELISA ALOS (Università Pompeu Fabra, Barcelona) terrà un seminario dal titolo "On smile properties of volatility derivatives and exotic products: understanding the VIX skew" Abstract. We develop a method to study the implied volatility for exotic options and volatility derivatives with European payoffs such as VIX options. Our approach, based on Malliavin calculus techniques, allows us to describe the properties of the at-the-money implied volatility (ATMI) in terms of the Malliavin derivatives of the underlying process. More precisely, we study the short-time behaviour of the ATMI level and skew. As an application, we describe the short-term behavior of the ATMI of VIX and realized variance options in terms of the Hurst parameter of the model, and most importantly we describe the class of volatility processes that generate a positive skew for the VIX implied volatility. In addition, we find that our ATMI asymptotic formulae perform very well even for large maturities. Several numerical examples are provided to support our theoretical results. -- Dott.
