by Peruggia, Mario 29 Sep '23

29 Sep '23

Please see below for details about four open positions in the Department of Statistics at The Ohio State University. My best, Mario Position Overview The Department of Statistics at The Ohio State University seeks to fill four tenure-track faculty positions at the following ranks: assistant (two positions), assistant or associate (one position), and open rank (one position). Successful candidates will be expected to contribute to the research, teaching and service missions of the department. Candidates with expertise in all research areas of statistics are encouraged to apply. Preferred areas of interest include (i) high-dimensional data; (ii) the foundations of data science; and (iii) complex dependence structures. We interpret each of these areas broadly. High-dimensional data analysis, for example, is motivated by modern, massive data sets that present computational, modeling, and/or statistical challenges. It is also motivated by data whose dimension is of the same order or exceeds the sample size. The foundations of data science include, for example, algorithmic modeling, large-scale computation, and theory for understanding algorithmic models and their evaluation, as well as related applications. Complex data structures include, as examples, data that are measured in space and time, live in non-standard spaces (functional data, shape data, network data), include individual heterogeneity (random effects), or have unmeasured covariates and unknown relationships (latent variable models). The appointment will be at a level commensurate with the applicant's experience. Applicants must specify the desired appointment rank in their cover letter. Education and Experience Requirements Required: A Ph.D. in Statistics or related field by the start of employment. Candidates should demonstrate a commitment to building a culturally diverse intellectual community, in line with OSU's Shared Values<https://oaa.osu.edu/shared-values-initiative>. Desired: We expect a commitment to methodological research and scientific collaboration and to the development and delivery of courses at both the undergraduate and graduate levels. Applicants at the Associate or Full rank are expected to have established an excellent record of research, mentorship, and service to the profession. How to Apply Please follow this link<https://osu.wd1.myworkdayjobs.com/OSUCareers/job/Columbus-Campus/Open-Searc…> for a full description of the position and application instructions. All qualified applicants will receive consideration for employment without regard to age, ancestry, color, disability, ethnicity, gender, gender identity or expression, genetic information, HIV/AIDS status, military status, national origin, pregnancy, race, religion, sex, sexual orientation, or veteran status.

LTI@UniTO Seminar: Diego Garcia | October 2, 2023 @ 12:00 - 13:00
by Luca Regis 29 Sep '23

29 Sep '23

Dear Colleagues, it is my pleasure to invite you to the following seminar in Quantitative Finance, organised by LTI@UniTO (www.carloalberto.org/lti) and Collegio Carlo Alberto (CCA), which will take place at CCA in Torino and can be followed via Zoom. At the event page link you can find the zoom link to attend online and a button to add the event to your calendars. ------------------------------------------------------------------------------------------- October 2nd @ 12.00 Speaker: Diego Garcia (University of Colorado Boulder) Title: New Consumption in the Wild Abstract: We study how market returns shape news consumption, employing 700 million pageviews over 27 months from Australia’s largest financial newspaper, the Australian Financial Review. Aggregate news consumption intensifies on days when the Australian market index decreases, led by a dramatic spike in consumption of markets news. By contrast, firm-specific news consumption declines when the aggregate market moves more (up or down). These findings imply aggregate and firm-specific news are substitutes for one another, consistent with theories of limited attention. These news consumption effects are strongest for fresh news, but they are also present for stale news articles on days when there are no articles about the firm. Joint with Tony Cookson and Elvis Jarnecic Event webpage link: https://www.carloalberto.org/event/diego-garcia-university-of-colorado-boul… Zoom link: https://us02web.zoom.us/j/89773170403?pwd=UDZDMS9BSzU5ckxqWG1yOGVzSkZzZz09#… <https://us02web.zoom.us/j/86924691100?pwd=TGcxeGpoM0dTR1FxaU9hQVM1SmlnUT09> Best regards, Luca Regis

Fwd: Lezione LEONARDESCA - DUMINIL-COPIN - 9 ottobre
by Maurizia Rossi 27 Sep '23

27 Sep '23

Cari tutti, Ricevo e inoltro con piacere. Cordiali saluti, MR ---------- Messaggio inoltrato --------- Da: Kevin Ray Payne <kevin.payne(a)unimi.it> Data: mer 27 set 2023 alle 16:24 Oggetto: Lezione LEONARDESCA - DUMINIL-COPIN - 9 ottobre A: *Lezioni LEONARDESCHE * Lunedì 9 ottobre 2023, ore 16.30, in Sala Adunanze dell’Istituto Lombardo, Academia di Scienze e Lettere, Palazzo Brera, in Via Brera 28 <https://www.google.com/maps/search/Via+Brera+28?entry=gmail&source=g> il Professore *HUGO DUMINIL-COPIN* *IHES and Université de Genève * parlerà su *Critical Phenomena through the Lens of the Ising Model * ABSTRACT: The Ising model is one of the most classical lattice models of statistical physics undergoing a phase transition. Initially imagined as a model for ferromagnetism, it revealed itself as a very rich mathematical object and a powerful theoretical tool to understand cooperative phenomena. Over one hundred years of its history, a profound understanding of its critical phase has been obtained. While integrability and mean-field behavior led to extraordinary breakthroughs in the two-dimensional and high-dimensional cases respectively, the model in three and four dimensions remained mysterious for years. In this talk, we will present recent progress in these dimensions based on a probabilistic interpretation of the Ising model relating it to percolation models. ABOUT THE SPEAKER: Hugo Duminil-Copin is a dynamic, energetic, and collaborative mathematician whose numerous contributions to statistical physics have justifiably earned him worldwide recognition and numerous awards. His work has centered on using ideas from probability theory to study the critical behavior of various models on networks. His work has revolutionized our understanding of percolation theory by identifying the critical point at which phase transitions occur and by characterizing the behavior of the system above, below and at the critical point. For his many and profound contributions to the understanding of probabilistic models at or near the critical point, Duminil-Copin was awarded the Fields Medal in 2022. Duminil-Copin received his Ph.D at the Université de Genève in 2012 under the direction of fellow Field’s Medalist Stanislav Smirnov with a thesis that exploited percolation theory and combinatorics to investigate the number of self-avoiding walks in hexagonal lattices that was published in the Annals of Mathematics. A series of prestigious prizes followed, including the Rollo Davidson Prize (2012), the Oberwolfach Prize (2013), the European Mathematical Prize (2016) and many others before receiving the Fields Medal. Duminil-Copin is Full Professor at the Université de Genève since 2014 (just two years after the Ph.D) and Permanent Professor at the IHES since 2016.

Reminder :: DEMS Bicocca Statistics seminar - Victor M. Panaretos - September 27th at 12 pm
by Alessia Caponera 25 Sep '23

25 Sep '23

Dear colleagues, We remind you about the seminar of Victor M. Panaretos (EPFL), on *Wednesday the* *27th of September at 12:00 pm*, at the University of Milano-Bicocca, Department of Management, Economics, and Statistics (DEMS). The seminar will be held in presence at the DEMS seminar room 2104 (building U7 Civitas, 2nd floor). ******************************************************* *Time: *Wednesday September 27th, at 12:00 pm *Place: *University of Milano-Bicocca | DEMS | Room 2104 (building U7 Civitas, 2nd floor) *Title: *Graphical Models for Stochastic Processes *Speaker:* Victor M. Panaretos (Institute of Mathematics, EPFL) *Abstract:* Graphical models allow us to distinguish direct and indirect associations in data. They can be used as models or they can be the targets of inference, and have been extensively studied in many contexts, the most recent emphasis being in high-dimensional statistics. For the most part, one considers a collection of random vectors indexed by a finite or discrete set. The purpose of this talk is to explore what happens when we are interested in the associations within and between stochastic processes. In the first case, we are dealing with graphical models with uncountable rather than discrete index set. In the latter case, we are dealing with graphical models for finite collections of function-valued random variables. Such settings introduce conceptual challenges owing to the lack of infinite-dimensional analogues of familiar algebraic tools, such as matrix inverses and determinants. It will turn out that the two problems share commonalities but also notable differences. Based on joint work with Kartik Waghmare (EPFL) and Tomas Masak (EPFL). ******************************************************* Best wishes, Alessia Caponera

Seminar by G. Giacomin (LPSM Paris) in Padova
by Giorgia Callegaro 22 Sep '23

22 Sep '23

Dear all, you are kindly invited to attend the seminar given in Padova by Prof. G. Giacomin. Here are the details: * Date: 30 October 2023 * Room: 2AB40, Torre Archimede * Title: Products of random matrices and the statistical mechanics of disordered Ising chains * Abstract: A general issue in statistical mechanics is understanding the role of disorder: disordered models are models that are made more realistic by allowing the presence of impurities. We consider this question in the basic context of Ising spin chains with nearest neighbor interaction J and random external field (the disorder). The matrix transfer method allows to rewrite the model in terms of a product of random matrices: in particular, the free energy density coincides with the top Lyapunov exponent. I will explain why the limit of J tending to infinity is of particular interest. As a matter of fact, for this limit one finds in the physical literature a remarkable prediction based on a renormalization group approach (work of Daniel Fisher in the 90s). We (collaboration with Orphée Collin and Yueyun Hu) have recently proven this prediction in the case in which the external field is centered. I will explain the result and some ideas from the proof by highlighting the interplay that arises in this problem between the theory of random matrix products and stochastic analysis. The seminar will *only* be in presence.

Dear all, I am pleased to invite you to the seminar organised by the Department of Economics at Ca' Foscari University of Venice, which can be followed via Zoom. Time: Wednesday 27th of September, at 10.30 Location: Campus San Giobbe, Meeting Room 1 Zoom: https://www.unive.it/data/agenda/3/77644 Speaker: Melvyn Weeks (University of Cambridge) Title: Making Sense of Natural Language: Measuring Cultural Fit and Its Impact on Managerial Tenure Abstract: We create measures for managers' cultural fit using one of the latest machine learning technologies – the sentence embedding model - by analysing 11.5 million speeches in earnings calls. A better cultural fit is significantly and positively correlated with managerial tenure. We demonstrate that the effect of cultural fit on managerial tenure is causal using causal survival forests. Firms that hire culturally disruptive managers have lower future market values and performance. The stock market reacts positively to signals that indicate low cultural dispersion within the firm. -- Roberto Casarin, PhD Professor of Econometrics Ca' Foscari University of Venice San Giobbe 873/b - 30121 Venezia, Italy http://sites.google.com/view/robertocasarin/ https://www.unive.it/vera <https://www.unive.it/isba2024> https://www.unive.it/isba2024 -- Nota automatica aggiunta dal sistema di posta *Sostieni il futuro* Dona il tuo 5x1000 al Collegio Internazionale Ca' Foscari *FINANZIAMENTO DELLA RICERCA SCIENTIFICA E DELLA UNIVERSITÀ | CODICE FISCALE: 80007720271*

The talk will be streamed on Zoom https://chalmers.zoom.us/j/69069218828 Password: 594071 We are looking forward to seeing you next Thursday, best, Massimiliano on the behalf of the OneWorldABC Organisers Date: Thursday, September 28, 9am UK time Speaker: Carlo Albert<https://www.eawag.ch/en/about-us/portrait/organisation/staff/profile/carlo-…>, Swiss Federal Institute of Aquatic Science and Technology Title: Learning summary statistics for Bayesian inference with Autoencoders Abstract: In order for ABC to give accurate results and be efficient, we need summary statistics that retain most of the parameter-related information and cancel out most of the noise, respectively. For many scientific applications, we need strictly more summary statistics than model parameters to reach a satisfactory approximation of the posterior. Therefore, we propose to use a latent representation of deep neural networks based on Autoencoders as summary statistics. To create an incentive for the encoder to encode all the parameter-related information but not the noise, we give the decoder access to explicit or implicit information on the noise that has been used to generate the training data. We validate the approach empirically on two types of stochastic models, one being a member of the exponential family, the other one not. ------ Dr. Massimiliano Tamborrino Associate Professor Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

Seminars at Ca' Foscari University: Dimitris Korobilis, University of Glasgow
by Roberto CASARIN 22 Sep '23

22 Sep '23

Dear Colleagues, It is my pleasure to invite you to the seminar organised by the Department of Economics at Ca' Foscari University of Venice, which can be followed via Zoom. Time: Monday 25, at 12.15 Location: Campus San Giobbe, Meeting Room 1 Zoom: https://www.unive.it/data/33113/3/76558 Speaker: Dimitris Korobilis (University of Glasgow)Title: Monitoring Multicountry Macroeconomic Risk Abstract: We propose a multicountry quantile factor augmented vector autoregression (QFAVAR) to model heterogeneities both across countries and across characteristics of the distributions of macroeconomic time series. The presence of quantile factors allows for summarizing these two heterogeneities in a parsimonious way. We develop two algorithms for posterior inference that feature varying level of trade-off between estimation precision and computational speed. Using monthly data for the euro area, we establish the good empirical properties of the QFAVAR as a tool for assessing the effects of global shocks on country-level macroeconomic risks. In particular, QFAVAR short-run tail forecasts are more accurate compared to a FAVAR with symmetric Gaussian errors, as well as univariate quantile autoregressions that ignore comovements among quantiles of macroeconomic variables. We also illustrate how quantile impulse response functions and quantile connectedness measures, resulting from the new model, can be used to implement joint risk scenario analysis.

Seminario Woess 27 settembre ore 14:30 Milano-Bicocca
by Daniela Bertacchi 17 Sep '23

17 Sep '23

Università di Milano-Bicocca *AVVISO DI SEMINARIO* Il prof. Wolfgang Woess (TU Graz, Austria), mercoledì 27 settembre, alle ore 14:30, nella stanza 3014 del Dipartimento di Matematica e Applicazioni (terzo piano U5), terrà un seminario dal titolo *Boundary behaviour of branching Markov chains* *Abstract: * We study multitype branching Markov chains on denumerable state(= type) spaces in discrete time. It is supposed that the offspring distributions satisfy a uniform "L log L" moment condition with state-independent expected offspring number, and that the associated "base" Markov chain on the state space is transient and irreducible. Given the population at time n at the different states, we normalize it by dividing by its total number. The resulting empirical distribution is a random probability measure on the state space. Assuming that the latter is equipped with a "geometric" compactification with a boundary at infinity, a main focus is on the question whether the sequence of empirical distributions converges a.s. weakly to a random probability distribution on the boundary. This is joint work with Vadim A. Kaimanovich (Ottawa), to appear in Ann. Inst Poincare' Prob. Stat. There is related, parallel work by Candellero and Hutchcroft. Tutti gli interessati sono invitati a partecipare.
