The first goal is to provide sufficient conditions for posterior consistency. In addition to the well-known Kullback-Leibler condition on the prior, the true distribution and most probability measures in the support of the prior are required to possess moments up to an order which is determined by the order of the Wasserstein metric. We further investigate convergence rates of the posterior distributions for which we need stronger moment conditions. The required tail conditions are sharp in the sense that the posterior distribution may be inconsistent or contract slowly to the true distribution without these conditions. We apply the results to density estimation with a Dirichlet process mixture prior. ------------------------------------------------ Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats in collaborazione con il Collegio Carlo Alberto e rientra nel Complex Data Modeling Research Network midas.mat.uc.cl/network Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

by Fabio Rapallo 14 Oct '20

14 Oct '20

Buongiorno a tutti, segnaliamo (inoltrando il messaggio in calce) due importanti novita' nel campo della Statistica Algebrica: - l'introduzione del codice 62R01 per 'Statistica algebrica' nella 2020 MSC classification - il primo volume (numerato 11 in riconoscimento del passato della comunita' di Statistica Algebrica) della rivista Algebraic Statistics https://msp.org/astat/ Cordiali saluti Fabio Rapallo Eva Riccomagno Maria Piera Rogantin ============================ Dear friends, The year 2020 has been very trying for many members of our community, but we can't fail to acknowledge two very important milestones for the field of algebraic statistics: that the 2020 MSC classification now includes 62R01 for 'algebraic statistics', and that a new journal has been established! It is with great pleasure that we announce the availability of the first issue of “Algebraic Statistics (AStat)”: —> https://msp.org/astat <— DOI: 10.2140/astat.2020.11-1 The first volume---numbered 11 to honour the past work of this community---will consist of two issues with a total of 11 papers, 5 of which are available online now. The second issue is forthcoming soon. AStat will be free to read until the end of 2021; thereafter, it will be available through an MSP or Project Euclid subscription. All papers become freely available 5 years after publication. Our publisher, MSP, is a nonprofit corporation based in Berkeley, USA. We see AStat as a primary forum serving the broad community in a focused way. As an interdisciplinary endeavor, by definition, a concerted effort will be made for AStat to serve various constituents interested in and interacting with algebraic statistics. We invite the community to send their best work in algebraic statistics to be considered for publication here. This may include contributions which connect statistical theory, methodology, or application to the world of algebra, geometry, and combinatorics in ways that may not be labeled as traditional. Do enjoy reading the first issue, and we look forward to welcoming your contributions to AStat. On behalf of the entire editorial board, Sonja and Thomas Managing Editors of Algebraic Statistics --- Sent via EditFlow by Sonja Petrović <sonja.petrovic(a)iit.edu> ============================ -- Fabio Rapallo Dipartimento di Economia Universita' di Genova

R: R: Annuncio seminario Marta Sanz-Sole (fwd)
by Tiziano Vargiolu 13 Oct '20

13 Oct '20

---------- Forwarded message ---------- Date: Tue, 13 Oct 2020 09:57:12 +0000 From: michele giordano <g.michele(a)outlook.com> ------------------------- Dear all, This is an announcement of the: STAR Online Seminars. The seminar will be held on Friday 16. October from 11:00-12:00. You will recieve the link for the zoom room by registering for the seminar at the following link (https://nettskjema.no/a/159180). The lecture will last for 45 minutes + questions. This week's speaker is Marta Sanz-Sole from University of Barcelona, with the seminar: Stochastic wave equations with super-linear coefficients. Abstract: We consider a stochastic wave equation on $R^d , d \in {1, 2, 3}$, driven by a Gaussian noise in $(t, x)$, white in time. We assume that the free terms $b$ and $\sigma$ are such that, for $|x| \rightarrow \infty$, $|\sigma(x)| < \sigma_1 + \sigma_2|x| (\ln_+(|x|))^a , |b(x)| < \theta_1 + \theta_2|x| (\ln_+(|x|))^{\delta}$ , (1) where $\theta_2, \sigma_2 > 0, \delta , a > 0$, with $b$ dominating over $\sigma$. For any fixed time horizon $T > 0$ and with a suitable constraints on the parameters $a, \delta, \sigma_2$ and $\theta_2$, we prove existence of a random field solution to the equation and that this solution is unique, and bounded in time and in space a.s. The research is motivated by the article [R. Dalang, D. Khoshnevisan, T. Zhang, AoP, 2019] on a $1-d$ reaction-diffusion equation with coefficients satisfying conditions similar to (1). We see that the $L^\infty$- method used by these authors can be successfully implemented in the case of wave equations. This is joint work with A. Millet (U. Paris 1, Pantheon-Sorbonne). After the end of the seminar, you are invited to bring a cup of coffee or tea and have a chat in our ''Coffee in the Stars'' here you will have the chance to talk and interact with the other persons that attended the seminar, and have a digital "coffee break". We are looking forward to see you, online!

Junior researcher position in Statistics (Health Analytics) at Politecnico di Milano, Italy
by Laura Maria Sangalli 12 Oct '20

12 Oct '20

Please see the following announcement of a junior researcher (RTDa) position opening in the group of Applied Statistics at the Department of Mathematics, Politecnico di Milano. ————————————————————————————————————————— Dear colleagues, I would like to announce a *junior researcher* (RTDa) position opening in the group of Applied Statistics at the Department of Mathematics, Politecnico di Milano. Please kindly forward the following announcement to potential candidates. Best regards, Francesca Ieva ————————————————————————————————————————— *Junior Researcher position in Statistics * *Project title*: "Integration between study design and data analytics for generating credible evidence in the field of healthcare from heterogeneous sources of structured and unstructured data” ====================================================================== We are looking for a junior researcher (3 year contract, starting date is between Feb 2021 - March 2021) to join the research group of Applied Statistics working within the research plan between Politecnico and AstraZeneca. One key criticism of evidence-based medicine is that only a minority of patients benefits of even efficacious therapies, but all treated patients are exposed to the costs and potential harms of those therapies. As a result, the effect of any treatment is often uncertain in a specific patient. Personalized care and precision medicine are becoming the main perspectives for obtaining better health outcomes at sustainable costs. The activities will develop along these perspectives with particular focus towards integrating observational designs and big data analytics to obtain solid, reproducible evidence whose results are verifiable in terms of health and expenditure. To this end, the researcher will develop multiple lines of research on Health Analytics for monitoring the effect of innovative oncological drugs through Real World Data, in collaboration with highly qualified clinical research centers. The ideal candidate should have a background and skills in at least some of the following: - Data Science, Statistics, Health Economics, Applied Mathematics, Software/Mathematical Engineering. - Solid experience in the data management and data analysis with R, Python, Matlab or C++. - Working knowledge in at least one of the following topics: biostatistics, pharmacoepidemiology, applied statistics, health economics. The effort is of a collaborative nature so strong interpersonal and communication skills are required. Teaching for both statistics and medical programs will be required. Working language is Italian and English. **Deadline for applications** is *November 11th, 2020*. Information and details about procedure can be found at https://www.polimi.it/it/docenti-e-staff/bandi-e-concorsi/bandi-e-concorsi-… For any further information please send an e-mail to francesca.ieva(a)polimi.it<mailto:francesca.ieva@polimi.it>. ----------------------------------------------------------------------------------------------------------------------------------------------- —— Laura Maria Sangalli MOX - Dipartimento di Matematica Politecnico di Milano Piazza Leonardo da Vinci 32 20133 Milano - Italy tel: +39 02 2399 4554 fax: +39 02 2399 4568 email: laura.sangalli(a)polimi.it<mailto:laura.sangalli@polimi.it> url: http://mox.polimi.it/~sangalli
