Re: [EM] Bucklin and detecting the highest generalized median rank

2004-04-08 Thread Forest Simmons
Bucklin is sometimes described as the method which gives the win to the candidate with the highest median rank, analogous to Borda as the method that gives the win to the candidate with the highest average rank. The usual version of Bucklin uses only the crude median, and then (in the case of seve

Chris Benham posted an archived discussion as a criticism of Bucklin. Actually Bucklin isn't what is being discussed in that quote, and so it has no relevance to Bucklin's merit. By the way, if anyone knows of an example in which Buckling fails Independence from Clones, would they post it? Mik

[EM] Methods passing or failing INI

2004-04-08 Thread Richard Moore
