Jeffreys-prior penalty, finiteness and shrinkage in binomial-response generalized linear models
Ioannis Kosmidis, David Firth
Penalization of the likelihood by Jeffreys' invariant prior, or by a positive power thereof, is shown to produce finite-valued maximum penalized likelihood estimates in a broad cla…
Modelling rankings in R: the PlackettLuce package
Heather L. Turner, Jacob van Etten, David Firth +1
This paper presents the R package PlackettLuce, which implements a generalization of the Plackett-Luce model for rankings data. The generalization accommodates both ties (of arbitr…
Modeling outcomes of soccer matches
Alkeos Tsokos, Santhosh Narayanan, Ioannis Kosmidis +4
We compare various extensions of the Bradley-Terry model and a hierarchical Poisson log-linear model in terms of their performance in predicting the outcome of soccer matches (win,…
Mean and median bias reduction in generalized linear models
Ioannis Kosmidis, Euloge Clovis Kenne Pagui, Nicola Sartori
This paper presents an integrated framework for estimation and inference from generalized linear models using adjusted score equations that result in mean and median bias reduction…
Two-way sparsity for time-varying networks, with applications in genomics
Thomas E. Bartlett, Ioannis Kosmidis, Ricardo Silva
We propose a novel way of modelling time-varying networks, by inducing two-way sparsity on local models of node connectivity. This two-way sparsity separately promotes sparsity acr…
