IDLab blended workshop

Dmitry Dagaev presented the criticism of the Hankin rating formation model (2020) at the IDLab workshop

Dmitry Dagaev, Deputy Vice-Rector of the HSE University and Head of the Laboratory of Sports Studies, presented his new study analyzing the model's shortcomings for constructing a rating of tournament participants based on pairwise comparisons. In a recent article, Hankin (2020) proposed a model that includes draws in a standard model that only allows wins and losses. An artificial player (`a Draw monster') was added into a two-sided non-strategic contest, so that each game could be interpreted as a three-sided non-strategic contest; a win of a Draw monster means that the initial two-sided contest ends up in a draw. Dmitry provides several critical arguments why modelling draws with an artificial player in the Bradley-Terry framework seems to be not a good idea. 
For the first time since the beginning of the pandemic, the workshop was held not in an online format, but in a blended format, when some of the participants and the speaker were gathered in the audience, and some were connected via Zoom.
