  • At the end of August, the two-day final review meeting of the proposed Collaborative Research Centre ("Sonderforschungsbereich") NC3 — where Roland is one of the PIs — took place at the ZiF in Bielefeld. Fingers crossed that we'll receive the funding for this exciting initiative!

  • Roland, Jenny and Timo, together with Théo Michelot and Stacy DeRuiter, gave a workshop on hidden Markov models at the University of St Andrews, UK. Two very intense and fun days!

  • Roland was one of three guest editors for a JABES special issue on animal movement modelling, the papers of which are now all online. An overview of the contributions can be found here.

November 2016:

  • We created the virtual research group EcoHMM, the aim of which is to synthesise research on the application of hidden Markov models to ecological data, which we hope will lead to many successful future collaborations.

  • Jennifer Pohle, Timo Adam, Christian Schellhase and Roland Langrock participated in BI.teach, with Roland discussing some key aspects of good teaching.

June 2016:

  • Roland Langrock published a book with Chapman and Hall: Hidden Markov Models for Time Series — An Introduction Using R (2nd Edition).

  • Timo Adam has joined the group as a PhD student. Timo wrote his Master's thesis on nonparametric methods for Markov-switching regression models and is going to continue working in this area during his PhD. Welcome Timo!

  • Jennifer Pohle gave a talk in the sociology seminar series "Quantitative Methods and Statistics" at Bielefeld University — the title of her talk was "Probit and mixed logit models for panel data - a theoretical and simulation comparison".

  • Roland Langrock gave a talk on HMMs to members of the chemical ecology group at Bielefeld University.

May 2016:

  • Odile Sauzet has joined the group. Odile will be in charge of the statistical consulting unit (StatBeCe). Welcome Odile!
  • Christian Schellhase attended the conference "Dependence Modeling in Finance, Insurance and Environmental Science" in Munich and gave a talk on "Nonparametric Estimation of Counterfactual Distributions for the Munich Rent Survey".

April 2016:

  • The Centre for Statistics (ZeSt) at Bielefeld University held a workshop for quantitative PhD students, with the students presenting and discussing their research. It is planned to have another such workshop in early October.

  • Roland Langrock gave a career talk to PhD students and postdocs at Bielefeld University — here are his slides (in German).

  • Paper accepted at Methods in Ecology and Evolution on the movement of the legendary wild haggis animal our R package for analyzing movement data using HMMs (link to the paper).

  • Jennifer Pohle has joined the group as a PhD student. She recently completed her MSc in Statistical Science here at Bielefeld University. Welcome Jenny!
