Elo rate

When a PD candidate receives multiple offers, often only one institution is accepted and the others are declined.
This is regarded as a competition between institutions, and the Elo-rating or Bradley-Terry model is introduced.
The basic definition is the same as that used in chess and shogi, where the difference between the rates of each institution determines the winning percentage.
We take the rate of DESY = 1000 as the basis and adopt maximum likelihood estimation for the Bradley-Terry model for 2006 - 2023 data.
