Web15 apr. 2024 · For a correct table, you cannot expect the P-value of fisher.test (2-sided as shown), to match results from phyper, which would be for a one-sided test. Suppose you have 600 subjects, of which 150 are in subgroups 450 are not. Then I guess you have 25 + 175 = 200 subjects involved in overlaps. Web17 okt. 2024 · In short, Fisher’s exact test relies on computing the p-value according to the hypergeometric distribution using binomial coefficients, namely via p = (n1 1 + n1 2 n1 1) (n2 1 + n2 2 n2 1) (n1 1 + n1 2 + n2 1 + n2 2 n1 1 + n2 1) Since the computed factorials can become very large, Fisher’s exact test may not work for large sample sizes. christopher jackson manchester

WebGiven the universe details and the sample size, the usual 'chi-square' statistic, though discrete, will be quite well approximated by a chi-square distribution when the number of red balls in the sample is hypergeometric. It's not exact, but it will be quite close in this case. Share Cite Improve this answer Follow edited Mar 1, 2013 at 5:57 WebThese calculated probabilities are referred to as ‘p-values’. Smaller p-values point to an interesting result only if all of the assumptions used to compute the p-value are valid The possibilities are not endless Let us return to the gene expression analysis example.
