Seminari di probabilità e statistica matematica
by Piccioni, Mauro 01 Mar '17

01 Mar '17

Lunedì 6 marzo Ore 16:00, Aula di Consiglio Seminario di probabilità e statistica matematica Mauro Piccioni Conditional iid structures in exchangeable multivariate distributions: from Marshall-Olkin to “load sharing” models The discovery of a conditional iid structure allows the understanding of the dependence contained in a d-variate distribution as generated by an exogenous latent factor . According to the celebrated de Finetti ‘s theorem this is equivalent to the possibility of defining an infinitely exchangeable sequence of random variables with the given d-marginal. In parametric classes of multivariate distributions, the determination of the values of the parameter corresponding to a structure of this type is a difficult problem which have been solved only in a few cases. In the talk the elegant theory developed by Mai and Scherer for the Marshall-Olkin distribution will be reviewed and some partial results for “load-sharing” models will be presented (joint work with Gerard Letac and Fabio Spizzichino). Tutti gli interessati sono invitati a partecipare. I seminari proseguiranno durante il secondo semestre ogni lunedì con cadenza settimanale.

Seminario Maren Schmeck a Padova
by Tiziano Vargiolu 27 Feb '17

27 Feb '17

Carissimi, il giorno martedi' 28 febbraio alle ore 15 presso il Dipartimento di Matematica dell'Universita' di Padova, via Trieste 63, sala Riunioni VII piano, la dott.ssa Maren Diane Schmeck dell'Universita' di Colonia terra' un seminario dal titolo ELECTRICITY PRICE MODELING WITH STOCHASTIC TIME CHANGE (joint with SVETLANA BOROVKOVA (VU AMSTERDAM)) ABSTRACT. In this paper, we develop a novel approach to electricity price modeling, based on the powerful technique of stochastic time change. This technique allows us to incorporate the characteristic features of electricity prices (such as seasonal volatility, time varying mean reversion and seasonally occurring price spikes) into the model in an elegant and economically justifiable way. The stochastic time change introduces stochastic as well as deterministic (e.g., seasonal) features in the price process? volatility and in the jump component. We specify the base process as a mean reverting jump diffusion and the time change as an absolutely continuous stochastic process with seasonal component. The activity rate of the stochastic time change can be related to the factors that influence supply and demand. Here we use the temperature as a proxy for the demand and hence, as the driving factor of the stochastic time change, and show that this choice leads to realistic price paths. We derive properties of the resulting price process and develop the model calibration procedure. We calibrate the model to the historical EEX power prices and apply it to generating realistic price paths by Monte Carlo simulations. We show that the simulated price process matches the distributional characteristics of the observed electricity prices in periods of both high and low demand.

Mini course in Verona - Simone Mattia Scotti: Real markets, microstructure, clusters and Hawkes with a Branching process point of view.
by Luca di persio 20 Feb '17

20 Feb '17

*Mini course announcement* Prof. Simone Mattia Scotti [ LPMA, Université Paris Diderot ] will give a mini course on *Real markets, microstructure, clusters and Hawkes with a Branching process point of view*, according with the following time table: 21st of March (2017) : Room I 1430-1730 23rd of March (2017) : Room M 1530-1730 24th of March (2017) : Room M 1430-1730 all the lessons will take place at the Dept. of Computer Science - UniVr Strada le Grazie, 15 - Verona Ca' Vignal located here https://goo.gl/maps/Yx2JU *Abstract and structure of the course* The analysis of real financial markets, along with the study of related economic time series, represents an increasing field of research and development of effective applications, from the stochastic processes point of views, as well as from the statistic and computational sides of the moon. In this mini-course, we first recall the classical framework behind the modern and mathematically rigorous, theory of finance, starting from the treatment of continuous-path stochastic processes. Then, we focus on the microstructure of market data, discussing both limit and market orders, along with correlated liquidity problems. In a second part, we will specialize our analysis on a particular feature of financial markets, namely the existence of jumps' cluster. It is worth to mention that the latter has been highlighted in recent literature in microstructure, showing to have a deep impact on real markets and representing a main research axis in the field. >From a mathematical point-of-view, we will first introduce point processes and then Hawkes processes. We will show that the self-exciting structure of Hawkes processes can easily explain some features exhibited by financial data, e.g. the cluster effects. In the third part, we will introduce the branching processes (CBI) showing that they can be seen as a natural extension (marked versions) of Hawkes processes. We will show that this class of models has very nice properties from computational as well as from analytical point of view, particularly by exploiting the Dawson-Li representation. Moreover, we will point out some unexpected features of the aforementioned approaches, such, e.g., the persistency of low interest rates and negative risk premium in electricity markets. A detailed bibliograpy will be given during the course. ___________ Do not hesitate to contact me for further details: luca.dipersio(a)univr.it LuCa -- __ Luca Di Persio - PhD assistant professor of Probability and Mathematical Finance Dept.

18 Feb '17

*Mini course announcement* Prof. Adrian Zalinescu [ Universitatea Alexandru Ioan Cuza - Iaşi, Romania ] will give a mini course on *Introduction to Stochastic Partial Di fferential Equations* (with applications to Finance, Biology, etc.), according with the following calendar 13 - 20 - 27 of March (2017) time table: from 1430 to 1730 all the lessons will take place at the Dept. of Computer Science - UniVr Strada le Grazie, 15 - Verona Ca' Vignal 2, first floor , *Room M* located here https://goo.gl/maps/Yx2JU The* tentative programme* is the following: 1. *Gaussian measure theory* Random vectors and Bochner integral. Some elements of probability in in nite-dimensional spaces are considered, with emphasis on the integration of random vectors with values in separable Banach-spaces and in operator spaces. Gaussian measures. We introduce cylindrical Gaussian random variables and Hilbert-spacevalued Gaussian random variables and then de ne cylindrical Wiener processes and Q-Wiener processes (i.e. with the covariance given by the trace-class operator Q) in a natural way. Stochastic integral and Ito's formula. The stochastic integral is constructed with respect to a cylindrical Wiener process, then with respect to a Q-Wiener process, by extending the integral of elementary processes. Some properties of the stochastic integral are given, including Ito's formula. 2. *Stochastic Di erential Equations* Semigroup Theory. In this section we review the fundamentals of semigroup theory. Stochastic Convolutions and Linear SPDEs. We derive existence and uniqueness of di erent types of solutions for linear SDEs driven by generators of C0-semigroups. The method is based on the study of the stochastic convolution. Solutions by Variational Method. The purpose is to study solutions of nonlinear SPDEs, which are seen as evolution equations in a Gelfand triplet, under assumptions of compact embedding or monotone coe cients. 3. *Applications* Along the abstract study of SDEs in in nite-dimensional spaces, various examples of SPDEs with applications in physics, biology and mathematical finance will be given. A detailed bibliograpy will be given during the course. ___________ Do not hesitate to contact me for further details: luca.dipersio(a)univr.it LuCa __ Luca Di Persio - PhD assistant professor of Probability and Mathematical Finance Dept.

Thursday 23 February from 12.00 to 13.00 LUISS room 207 viale Romania 32 00197 Roma. *Speaker:* Bruno Ziliotto (CNRS) *Title:* In zero-sum stochastic games, the payoff is constant *Abstract*: In a zero-sum stochastic game, at each stage, two adversary players take decisions and receive a stage payoff determined by these actions and by a random variable called state of nature. The total payoff is the discounted sum of the stage payoffs. Assume that players are very patient and use optimal strategies. We then prove that at any point in the game, players get essentially the same payoff: the payoff is constant. No game theory prerequisite of any kind is needed to understand this talk.

********************************************************************* SEMINARI DI PROBABILITA' E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITA' DEGLI STUDI DI TORINO ********************************************************************* mercoledì 15 Marzo 2017 alle ore 11:30 in Aula C presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. CARLO SGARRA (Politecnico di Milano) terrà un seminario dal titolo A BRANCHING PROCESS-BASED APPROACH TO POWER MARKETS (The talk will be mainly based on a joint paper with Y. Jiao, C. Ma and S. Scotti). Abstract: Energy markets, and in particular, electricity markets, exhibit very peculiar features. The historical series of both futures and spot prices include seasonality, mean-reversion, spikes and small fluctuations. Very often a stochastic volatility dynamics is postulated in order to explain their high degree of variability. After the pioneering paper by Schwartz, where an Ornstein-Uhlenbeck dynamics is assumed to describe the spot price behavior, several different approaches have been investigated in order to describe the price evolution. High frequency trading, on the other hand, introduced some new features in commodity prices dynamics: in a recent paper by V. Filimonov, D. Bicchetti, N. Maystre and D. Sornette evidence is shown of endogeneity and structural regime shift, and in order to quantify this level the branching ratio is adopted as a measure of this endogenous impact and a Hawkes processes dynamics is assumed as a reasonable modelling framework taking into account the self-exciting properties. The purpose of the present investigation is to propose a new modeling framework including all the above mentioned features, still keeping a high level of tractability. The model considered allows to obtain the most common derivatives prices in closed or semi-closed form. Here with semi-closed we mean that the Laplace transform of the derivative price admits an explicit expression. The models we are going to introduce can describe the prices dynamics in two different forms, that can be proved to be equivalent: the first is a representation based on random fields, the second is based on Continuous Branching Processes with Immigration (CBI in the following).

Il giorno 21 febbraio 2017 presso l'Aula E del Dipartimento di Matematica, Sapienza Università di Roma si terranno i seguenti seminari di Probabilità e Statistica Matematica: Ore 14.30 Wolfgand Woess (TU Graz, Austria) Multidimensional reflected random walk - some results and many questions Abstract: Let (Y_n,V_n) be i.i.d. distributed, with the components r and s-dimensional, respectively. Reﬂected random walk starting at a point x of the positive r-dimensional orthant is deﬁned recursively by X_0 = x, X_n = |X_{n−1}−Y_n|, where |(a_1,...,a_r)| = (|a_1|,...,|a_r|). In R^s, consider the ordinary sum S_n = V_1 +···+V_n . We are interested in (topological) recurrence of the process (X_n,v+S_n) starting at (x,v). While this is quite well understood for refelcted random walk with r=1, in higher dimension (r \geq 2) or with some non-reﬂected coordinates (s \in {1,2}) we have a few basic results and various open questions with some partial answers. This is work with Judith Kloas, with input from Marc Peigne' and Wojciech Cygan. Ore 15.30 Oriane Blondel (CNRS Lyon, France) More random walks on random walks Abstract: We consider a Poissonian distribution of particles performing independent simple random walks. Simultaneously, on top of this system, a random walker evolves with a drift to the right when it is on top of (at least) a particle, to the left when it is on an empty site. We obtain a LLN, CLT and large deviation bounds in high and low density. Joint work with Marcelo Hilario, Renato dos Santos, Vladas Sidoravicius, Augusto Teixeira.

Il giorno martedi' 21 febbraio alle ore 11 presso il Dipartimento di Matematica dell'Universita' di Padova, via Trieste 63, aula 1AD/100, il prof. Giorgio Ferrari dell'Universita' di Bielefeld, e ospite del Dipartimento di Matematica in qualita' di professore visitatore nell'ambito del progetto YITP (Young Investigation Training Program), terra' un seminario dal titolo Controlling Public Debt without forgetting Inflation Abstract -------- Consider a government that wants to control its debt-to-GDP (gross domestic product) ratio, while taking into consideration the evolution of the inflation rate of the country. The uncontrolled inflation rate follows an Ornstein-Uhlenbeck dynamics and affects the growth rate of the debt ratio. The level of the latter can be reduced by the government through fiscal interventions. The government aims at choosing a debt reduction policy which minimises the total expected cost of having debt, plus the total expected cost of interventions on debt ratio. We model such problem as a two-dimensional singular stochastic control problem over an infinite time-horizon. We show that it is optimal for the government to adopt a policy that keeps the debt-to-GDP ratio under an inflation-dependent ceiling. This curve is the free-boundary of an associated fully two-dimensional optimal stopping problem, and it is shown to be the unique solution of a nonlinear integral equation. Finally, some economic conclusions are drawn. Tutti gli interessati sono invitati a partecipare.

Il giorno giovedì 16 febbraio alle ore 16 presso il Dipartimento di Economia dell'Università di Perugia, la Dott.ssa Zehra Eksi, Assistant Professor presso la WU-Vienna University of Economics and Business, e ospite del Dipartimento di Economia in qualità di professore visitatore nell'ambito del progetto YITP (Young Investigation Training Program), terrà un seminario dal titolo "EM Algorithm for Markov Chains observed via Gaussian Noise and Point Processes Information" *Abstract*: In this paper we obtain an Expectation-Maximization (EM) algorithm for a setting in which the state variable follows a finite-state Markov chain observed via diffusive and point process information. Such a setting may arise, for example, in the modelling of sovereign credit risk where information stems from default history (jump component) and CDS spreads (diffusive component). Obtaining the EM algorithm amounts to the derivation of finite-dimensional filters for quantities such as number of jumps and sojourn times associated to the Markov chain. In this context, we obtain both exact and unnormalized filters for the related quantities. Moreover, we compute discretized robust versions of the unnormalized filters. Next, we introduce a novel goodness of fit test to check how well the estimated model explains a given data set. Finally, we run a simulation study to test speed and accuracy of the algorithm. In particular, we provide a comparison for the estimates resulting from the robust and naive discretization and the value of point process information (This is a Joint work with Camilla Damian and Ruediger Frey) Tutti gli interessati sono invitati a partecipare.

Nell'ambito del ciclo di seminari del Dipartimento di Scienze per l'Economia e l'Impresa (DISEI) dell'Universita' di Firenze, il giorno Martedì 14 Febbraio 2017 (Edificio D6/Aula Bracco, ossia 1.12): si terranno i seguenti 2 seminari ore 10 Francesca Lilla (Università di Bologna) OPTION PRICING WITH HIGH FREQUENCY ESTIMATES OF CONTINUOUS AND DISCONTINUOUS VOLATILITY COMPONENTS ore 11 Susana Martins, University of Minho & NIPE, Braga, Portugal MODELLING SOVEREIGN DEBT CONTAGION: A SMOOTH TRANSITION APPROACH Tutti gli interessati sono cordialmente invitati a partecipare. La lista dei seminari Disei è raggiungibile al seguente indirizzo: http://www.disei.unifi.it/vp-104-seminari.html Abstract dei seminari OPTION PRICING WITH HIGH FREQUENCY ESTIMATES OF CONTINUOUS AND DISCONTINUOUS VOLATILITY COMPONENTS Jump-diffusion model represents the popular approach to match return stylized facts. Its estimation is simplified since prices are observable quantities, but it does not appear to be sufficient to yield the rapid increases in volatility which have been historically experienced. Examining price evolution at ultra high frequency, traditional measures of jump variation tend to spuriously assign a burst in volatility to the jump components. What jump-diffusion model identifies as genuine price jumps are period of heightened volatility. Starting from these findings, I develop a new multifactor volatility model, labeled as VARG-J, in which volatility is decomposed in two components: continuous and discontinuous. The first involves small changes while the second occasional big moves. The VARG-J model belongs to the class of affine discrete-time models based on high frequency volatility measures. The pricing approach performed in this paper allows to incorporate risk premia in order to compensate for two new sources of risk concerning both volatility components, beyond the risk related to shocks in log-returns. Combining high-frequency returns and option data, the empirical analysis illustrates that volatility jump component is a key ingredient for reproducing the observed volatility smile and for improving the pricing performances of S&P 500 Index options. MODELLING SOVEREIGN DEBT CONTAGION: A SMOOTH TRANSITION APPROACH ABSTRACT: In this paper, we study the timing and extent of the European sovereign debt contagion across nine Eurozone countries from 2005 until 2016. In this setting, financial contagion is measured as a significant increase in cross-market correlations which are assumed to follow a Smooth Transition Conditional Correlation (STCC-) GARCH model. The cross-market correlations change smoothly between two extreme states according to an observable transition variable. This variable is specified both as a function of time and lagged returns. When using time, a pre-crisis and two crises sub-periods are identified. Our results suggest contagion effects within the periphery countries, notably from Greece and Portugal, and between the periphery and core countries.

Alcuni aggiornamenti sulla lista Random
by Marco Romito 06 Feb '17

06 Feb '17

Cari iscritti, alcune informazioni importanti relative alla lista Random. 1) C'è stato un piccolo problema tecnico sul server che ospita la lista (più dettagli in calce per gli interessati) per cui alcuni dei messaggi inviati tra il 26 gennaio ed il 5 febbraio potrebbero non essere stati recapitati a tutti gli iscritti (essenzialmente, non hanno ricevuto messaggi coloro la cui posta in un modo o nell'altro passa attraverso server Google). Il problema è attualmente risolto. 2) L'archivio dei messaggi inviati su Random è disponibile all'indirizzo seguente (riportato in calce a ogni messaggio inviato sulla lista): https://fields.dm.unipi.it/pipermail/random/ Chi invia un messaggio a Random è invitato a controllare tale archivio 15 minuti dopo l'invio, per assicurarsi che il proprio messaggio sia effettivamente passato. (Talvolta capita che chi invia un messaggio non lo riceva al proprio indirizzo. Se il messaggio compare in archivio, gli altri utenti lo hanno ricevuto.) 3) L'indirizzo a cui inviare i messaggi alla lista è random(a)fields.dm.unipi.it Ricordiamo che è importante inviare i messaggi dall'indirizzo con cui si è iscritti a Random, altrimenti i messaggi vengono bloccati. Buona giornata, Francesco e Marco _Dettagli tecnici per gli interessati_: nel fine settimana del 27-28 gennaio il numero IP del server che ospita la lista è stato cambiato. Contestualmente, il tecnico che gestisce il server ha attivato la posta sull'indirizzo IPv6 (e non su IPv4). In teoria nulla di grave, perché l'architettura attuale dei server (dns, etc) permette l'indirizzamento con entrambi i tipi. Purtroppo i server di Google si aspettano che il DNS abbia anche una chiave crittografica per garantire che l'indirizzo IPv6 in questione sia autorizzato a inviare posta. Questo, tragicamente, non è stato fatto dal tecnico. La soluzione più immediata è stata di riportare la posta sull'indirizzo IPv4.

03 Feb '17

ll giorno lunedì13 febbraio alle ore 11.00 presso la aula seminari del Dismeq al IV piano dell'edificio U7, il prof. Emilio Porcu del Department of Mathematics della University Federico Santa Maria di Valparaiso terrà un seminario su Estimation and Prediction using Wendland covariance functions under Infill Asymptotics Abstract We study estimation and prediction of Gaussian random fields with covariance models belonging to the generalized Wendland (GW) class, under fixed domain asymptotics. As the Matlern case, this class allows a continuous parameterization of smoothness of the underlying Gaussian random field, being additionally compactly supported. The paper is divided into two parts: first, we characterize the equivalence of two Gaussian measures with GW covariance function, and we provide sufficient conditions for the equivalence of two Gaussian measures with Matlern and GW covariance functions. We elucidate the consequences of these facts in terms of (misspecified) best linear unbiased predictors. In the second part, we establish strong consistency and asymptotic distribution of the maximum likelihood estimator of the microergodic parameter associated to GW covariance model, under fixed domain asymptotics. Our findings are illustrated through a simulation study: the former compares the finite sample behavior of the maximum likelihood estimation of the microergodic parameter with the given asymptotic distribution. The latter compares the finite-sample behavior of the prediction and its associated mean square error when using two equivalent Gaussian measures with Matlern and GW covariance model, using covariance tapering as benchmark. Tuti gli interessati sono invitati a partecipare.

Indeed, the volatile demand, the strong seasonality of sales, the wide number of items with short life cycle or the lack of historical data, make the traditional forecasting models, based on time series, unsuitable or at least very difficult to implement. Therefore, researchers and practitioners have investigated other techniques such as Artificial Intelligence. The emergence of the “big data” era has also opened new opportunities and generated new issues. In this presentation, we propose an overview of the different constraints related to the sales forecasting in the fashion industry. Some examples are introduced to illustrate the problematics and the potential solutions. Finally, the new opportunities which could be explored are discussed. -- --------------------------------------------------- Roberta Sirovich Department of Mathematics G.

Numerical methods for stochastic models: control, uncertainty, quantification, mean-field
by Tiziano Vargiolu 30 Jan '17

30 Jan '17

Numerical methods for stochastic models: control, uncertainty quantification, mean-field July 17 - August 25, CIRM, Marseille http://smai.emath.fr/cemracs/cemracs17/ The goal of this event is to bring together scientists from both the academic and industrial communities and discuss these topics. During the first week, a classical summer school is proposed. It consists of several lectures given by leading scientists and related to the topics of the research projects. The remaining 5 weeks are dedicated to working on the rechearch projects, possibly after a morning seminar. Cemracs'17 will be the twenty-second of the series, devoted this year to the study of advanced numerical methods for the analysis of stochastic models associated with stochastic control problems, uncertainty propagation analysis or mean-field type interaction phenomena. These models are echoes many industrial applications (production optimization systems, life sciences, neuroscience, geophysics, fluid mechanics, risk management in finance, etc.). The main difficulty is the non-linearity or the high dimension of the problems encountered in practice. -- Stefano Pagliarani, DEAMS, Universit? di Trieste Via Tigor 22, 34124 Trieste, Italy Cell.

PEANO" UNIVERSITA' DEGLI STUDI DI TORINO ********************************************************************* *Giovedì 9 Febbraio 2017 alle ore 11:00 in Aula C* presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, si svolgerà il seguente seminario Sales forecasting in fashion industry: main issues and opportunities Sébastien Thomassey ENSAIT – Lille 1 University Roubaix – France *Abstract *The fashion industry is a very challenging market for the sales forecasting. Indeed, the volatile demand, the strong seasonality of sales, the wide number of items with short life cycle or the lack of historical data, make the traditional forecasting models, based on time series, unsuitable or at least very difficult to implement. Therefore, researchers and practitioners have investigated other techniques such as Artificial Intelligence. The emergence of the “big data” era has also opened new opportunities and generated new issues. In this presentation, we propose an overview of the different constraints related to the sales forecasting in the fashion industry. Some examples are introduced to illustrate the problematics and the potential solutions. Finally, the new opportunities which could be explored are discussed. r. -- --------------------------------------------------- Roberta Sirovich Department of Mathematics G.

Avviso di seminario al Politecnico di Milano
by Giuseppina Guatteri 27 Jan '17

27 Jan '17

Si avvisa che in data 3/2/2017, alle ore 12:00 precise, presso Aula seminari del terzo piano del dipartimento di Matematica del Politecnico di Milano, nell'ambito delle iniziative della sezione di Probabilità e Statistica Matematica, si svolgerà il seguente seminario: Titolo: MIsure invarianti per l'equazione stocastica di Navier-Stokes nel piano/ Invariant measures for Navier Stokes equation in the plane Relatore: Benedetta Ferrario, Universita' di Pavia Abstract: Si presenta un risultato di esistenza di una misura invariante per l'equazione di Navier-Stokes nel piano con forzante di tipo rumore bianco nel tempo. Poiche' si lavora in un dominio spaziale illimitato, l'immersione dello spazio di Hilbert H^1 in H^0 non e` compatta e questo richiede una tecnica diversa dal caso di dominio spaziale finito per la dimostrazione dell'esistenza di una misura invariante. Invece del metodo di Krylov e Bogoliubov si ricorre al metodo di Maslowski e Seidler (On sequentially weakly Feller solutions to SPDE's. Atti Accad. Naz. Lincei, Cl. Sci. Fis. Mat. Natur. Rend. Lincei (9) Mat. Appl. 10 (1999), no. 2, 69-78). Questo lavoro e` in collaborazione con Z. Brzezniak (Universita` di York). The existence of an invariant measure for 2d Navier Stokes with white noise (in time) forcing term is given. Due to the unboundedness of the domain a different technique in proving this existence result used. In fact, rather then using Krylov-Bogoliubov method we follow the approach introduced by Maslowsly and Seidler (On sequentially weakly Feller solutions to SPDE\'s. Atti Accad. Naz. Lincei, Cl. Sci. Fis. Mat. Natur. Rend. Lincei (9) Mat. Appl. 10 (1999), no. 2, 69-78). This is a joint paper with Z. Brzezniak, University of York. Tutti gli interessati sono invitati a partecipare.
