Hi.
Have you checked the results of your code for Fisher's Exact Test? I don't think it produces correct results. Here's a utility that produces results identical to those I calculate: http://www.exactoid.com/fisher/index.php This expression at the beginning of your code seems odd: It simplifies to: $test = $a*$d  $b*$c; I don't follow why you have this: For example, if a = 1, b = 50, c = 10 and d = 5, P(onesided) = P(twosided) = 1.4386e07, not 1. Nevertheless, thanks for the tip about calculating factorials only once. Let me know if I've misunderstood something. In reply to Re: Fisher's Exact Test
