Hi all, In line of some of the results posted here, I'd like to make some people aware of the existance of the 'Whoisbetter' utility. It is a program by Steve Maughan (http://home.clara.net/maughan/) that can aid you in determining whether a certain result has any statistical meaning. It's a bit unfortunate there is little explication of the used mathematics :( It only says it is based on the binominal distriubtion. If anyone has an idea on how it could work, please post, as I will begin working on a similar program but based on other mathematics soon. A little table for those who can't run Windows programs: The winning program must at least have the 'required' score to be able to say it is better with standard statistical significancy. Played games Required score ----------------------------------- 5 5 - 0 10 8 - 2 15 11 - 4 20 14 - 6 30 20 - 10 50 31 - 19 100 59 - 41 200 113 - 89 So for example, if you play a match between 2 programs and one scores 7-3, you _can't_ say that the winner is stronger. Well, you can, but there are people that are selling rings that make you live forever, which are proven to work based on the same kind of highly reliable science. -- GCP
