The first YUIMA Summer School on Computational and Statistical Methods for Stochastic Process & Third Yuima Workshop*

This 4 days course aims at introducing researchers, PhD students and practitioners to several aspects of modern numerical and statistical analysis of time series through the R language and, in particular, the YUIMA package.

The course covers topics of R programming, time series data handling, simulation and numerical analysis for several types of statistical models including: point processes, Hawkes processes,stochastic differential equations driven by Brownian motion with or without jumps, fractional Brownian motion and Lévy processes.

* Program to be announced, by invitation only

Who can benefit?

Stochastic differential equations, with or without jumps, are nowadays used as statistical models in many contexts, including but not limited to, finance, insurance, phylogenetics, genomics, political analysis, economics, migration flow analysis, social network analysis, and more. They are continuous-time models fitted on discrete sampled data. Point processes, like Compound Poisson and Hawkes processes are used in Limit Order Book (LOB) analysis in trading and finance, as well as in the analysis of rainfalls in meteorology or in earthquakes analysis in seismology. Jump and Lèvy processes extends many of the above models to a variety of statistical distributions that are able to capture stylised facts about real time series. Last, but not least, fractional processes are typical tools of climate change studies. Although the course could not cover all of the above applications, the participants can benefit from understanding the simulation and estimation techniques for these classes of stochastic process and apply to their own research field with the help of the faculties of this summer school.

Students are admitted for free! But we have a limited number of slots, register soon!

Due to high requests, registration has been extended to May 31st 2019. Hurry up!

Should I pay VAT?

Due to Italian regulation (DPR 663/72 art.7) and EU fiscal regulations, the total cost for the participant attending this course has to include VAT (IVA in italian) of 22%. This rule applies to all “entities”: profit and non-profit companies and/or institutions and citizens even when special fiscal treatments exist in the original country of the “entity” unless your company or institution is registered into the VIES system.

Please notice: if you pay on behalf of your organization as a private citizen, i.e. from your personal bank account, then you have to add VAT anyway even if your organization is registered into the VIES system (as VAT is calculated for the actual “payer/buyer”). In this case it is better to ask us before paying.

To know about your VIES status, please follow the steps below:

VIES Verification

To check your VIES status, follow these steps:

  1. Ask your administration for the VAT number
  2. Go to this web page http://ec.europa.eu/taxation_customs/vies/?locale=en
  3. Select your country from the top-down menu
  4. Put the VAT number (without the country code) and press the button “verify”
  5. Email the output of the above screen along with your complete data to [email protected] and ask us to invoice your company/institution

Venue

We will welcome you on Tuesday around 8:30h for the registration at the main site (1) where we will distribute the course material.

On the same day there will be a Welcome dinner buffet from 18:30 to 20:30. The main idea of this welcome meeting is to have the opportunity to chat each other in an informal environment. Please note: there will be food and drinks to satisfy your hunger and thirst, and later we can move on into the town in smaller groups to enjoy the many beergardens and restaurants.

Conference sites

The following map is a very reduced one. You can have a big one in PNG format, or you can browse an interactive one from the web page of the Tourist Office in Bressanone-Brixen.

(1) Casa della Gioventù – main course site:

Casa della Gioventù is the place where both morning lectures and laboratory will take place, and it is also the place of the Welcome Buffet.

It is a building of the University of Padova, located in Via Rio Bianco 6, 5 minutes from the town center.

(2) Hotel Albero Verde (Grüner Baum):

It is a hotel were many of the participants usually stay.

(3) The railway station:

Travel & Accommodation

How to get to Bressanone – Brixen

Bressanone(or Brixen) is in the bilingual province of Bolzano (Bozen) at 500 meters of altitude, in the Italian Alps, close to the Dolomites.

View Larger Map

By Train

Bressanone is on the international line between Munich (Germany) and Verona (Italy). Every train on this line stops in Bressanone. Moreover, there are many commuter connections from Innsbruck (Austria) and from Bolzano (Italy) to Bressanone.

The train from Verona P.ta Nuova to Bressanone takes about 2 hours, with frequent connections throughout the day. The train from Munich takes about 3.5 hours, with connections every 2 hours.

By Airplane

Several airports have good train connections to Bressanone:

  • Bolzano, Italy (BZO) 50 km(30 minutes by train)
  • Innsbruck, Austria (INN) 80 km(1 hours by train)
  • Verona, Italy (Valerio Catullo, VRN) 200 km
  • Munich, Germany (Franz-Josef Strauss, MUC) 260 km
  • Venezia, Italy (Marco Polo, VCE) 320 km
  • Milano-Linate, Italy (LIN) 330 km
  • Milano-Malpensa, Italy (MXP) 350 km

The closest large airport is Verona (Valerio Catullo) international airport. From Verona airport to the railway station Verona P.ta Nuova there are shuttle busses every 20 minutes from 6:30am to 11:35pm. From Verona to Bressanone it takes about 2 hours by train, and you have several trains per day.

About Munich: please do not confuse Munich’s main airport (Franz-Josef Strauss) with Ryanair’s “Munich West” (Memmingen) – it is far out in the Allgäu, and it is not much fun coming from there by public transport; with a rental car, it may however be an option.
