Fitting a choice model (Bradley-Terry generalization)
...iments use different comparisons.
The problem is a generalization of Bradley-Terry but it differs from
some generalizations in that the comparisons are not pairwise, and they
don't produce a full ordering, just that one is preferred to the other
four possibilities.
I have had a look at the BradleyTerry2, eba, pmr and MLCM packages, none
of which appear to provide the required functionality. I have also
looked at a number of papers (Hunter, 2004; Firth, 2005; Huang Weng and
Lin, 2006; and Fujimoto, Hino and Murata 2011). I think fitting using
maximum likelihood should be possible, but would wel...

I am trying to run a very large Bradley-Terry model using the BradleyTerry2 package. (There are 288 "players" in the BT model).
My problem is that I ran the model below successfully.
WLMat is a win-loss matrix that is 288 by 288
WLdf<-countsToBinomial(WLMat)
mod1<-BTm(cbind(win1,win2),player1,player2,~player,id="player",data=WLdf)
Then I need...
