     There are four players, p1 to p4.  These players play doubles
     tennis matches with the following results:

             match         score
       {p1,p2} vs {p3,p4}   9-2
       {p1,p3} vs {p2,p4}   4-4
       {p1,p4} vs {p2,p3}   6-7
          {p1} vs {p3}     10-14
          {p2} vs {p3}     12-14
          {p1} vs {p4}     10-14
          {p2} vs {p4}     11-10
          {p3} vs {p4}     13-13

     It is suspected that p1 and p2 have some form of team cohesion and
     play better when paired than when either solo or with other
     players.  As the scores show, each player and, apart from p1-p2,
     each doubles partnership, is of approximately the same strength.

     Dataset 'doubles_noghost' gives the appropriate likelihood
     function for the players' strengths; and dataset 'doubles' gives
     the appropriate likelihood function if the extra strength due to
     team cohesion of {p1,p2} is represented by a ghost player.
