News & Activities


  • Peter co-authored a replication paper comparing different decision criteria when testing if a population mean is practically equivalent to a point null hypothesis. The paper was accepted for publication in Journal of Comments and Replications in Economics.
  • A paper discussing pitfalls in meta-studies on p-hacking and publication bias, co-​authored by Peter, was accepted for publication in the American Economic Review.
  • Julia and Odile built the R package EgoCor to explore spatial correlation structure in health data by fitting and visualizing exponential semi-variogram models. The package is now available on CRAN.


  • The German Research Foundation (DFG) approved another four years of funding of the Collaborative Research Centre ("Sonderforschungsbereich") SFB-TRR 212. Our group will be involved with one postdoc position.
  • In the winter term, Marius will be Interim Professor of Data Science and Applied Statistics at the TU Clausthal.
  • Sina's paper on continuous-time capture-recapture modelling was accepted for publication in the Annals of Applied Statistics.
  • A new hot hand paper by Sina and Marius, considering basketball & continuous-time modelling, was accepted for publication in AStA Advances in Statistical Analysis.
  • Julia Dyck has joined the group as a PhD student.
  • Jenny handed in her PhD thesis and has directly started a postdoc at BioMove in Potsdam.
  • A paper by Marius looking into a possible hot shoe in penalty talking, analysed using regularisation techniques within HMMs, was accepted for publication at Statistical Modelling.
  • Jenny & Timo built the R package PHSMM for estimating HSMMs without having to specify a class of distributions for the dwell times. The package is now available on CRAN.


  • Jenny has a new preprint on the arXiv, in which an effectively nonparametric method is developed for estimating the dwell-time distributions in HSMMs.
  • Sina and Marius have another new preprint on the arXiv, in which they analyse >100K free throws taken in the NBA to once and for all decide if there is a hot hand effect.
  • We have a new preprint on the arXiv, in which we propose and discuss a very general class of state-space models formulated in continuous time.
  • We have a new group member, Peter Pütz, who joins the group as a postdoc.
  • Roland will be a PI within EPOC ("Economic Policy in Complex Environments"), a new Marie Skłodowska-Curie Innovative Training Network across the EU, with partner universities in Amsterdam, Barcelona, Copenhagen, Paris, Venice and Milano.


  • Roland was a guest editor of a METRON special issue on HMMs — here is the editorial giving an overview of the papers.
  • Sina won the best student presentation award at the IWSM 2019 in Guimarães.
