Talk:Permutation test: Difference between revisions

 

: I'm currently using "all combinations", which is reasonably fast (though I'm careful to treat each sample point independently, just in case there are repeated samples). All permutations is much slower (or it is if you generate directly) and I'm not sure how much difference it should make to the result since you'd effectively just be multiplying the number of each count by <math>m!n!</math> (== 1316818944000 in this example; we'd be waiting a while for the result) and then dropping all that anyway when you average out. –[[User:Dkf|Donal Fellows]] 21:46, 1 February 2011 (UTC)
