News & Activities

2022

  • A paper resulting from a project within last year's Statistical Consulting course, co-authored by four students from the MSc Statistical Science (and Roland), was accepted for publication in Limnology and Oceanography Letters. The paper investigates how seabirds exploit dynamic ocean features for foraging.
  • 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.

2021

  • 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.

2020

  • 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.

2019

  • 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.
