FisherвЂ™s Exact Test (Scripts) Publisher's description
from Michael Boedigheimer
Matlab's implementation of Fisher's exact test only supports one-tailed tests
Matlab's implementation of Fisher's exact test only supports one-tailed tests. Other implementations on the file exchange are reportedly buggy and are far too slow for problems I'm working on. This implementation does 2.5e6 one or two-tailed tests per second and is ideally suited for genome-wide association studies or other large problems where 100s of samples and 10s to 100s of 1000s of tests are being performed.
It has been verified correct for samp les sizes up to 100 and spot checked beyond that up to 1000s of samples.
