Abstract: Linear paired comparison models are studied when ties or draws are allowed, where the probability of a win plus half the probability of a draw is modelled as a symmetric cumulative function evaluated at the difference of strength parameters. These models are extended to make use of covariate information and used for ranking 64 top chess players since 1800 with information on career periods. The Davidson model which allows for draws does not fit chess data well because of the large variability in draw percentages from player to player. Some new methodology including an analysis of an appropriate goodness‐of‐fit test is given for this extended use of the linear model.
