WebNov 2, 2015 · Hypergeometric test. In a first time, we model the association between genes and GO class using a hypergeometric distribution. The classical example for the hypergeometric is the ranomd selection of “k” balls in an urn containing “m” marked and “n” non-marked balls, and the observation that the selection contains “x” marked ball.

Hypergeometric distribution probabilities using R - VRCBuzz

Webdhyper gives the density, phyper gives the distribution function qhyper gives the quantile function and rhyper generates random deviates. The hypergeometric distribution is used for sampling without replacement. It has density p(x) = choose(m, x) choose(n, k-x) / choose(m+n, k) WebYou are close, with your use of dhyper and phyper, but I don't understand where 0:2 and -1:2 are coming from. The p-value you want is the probability of getting 100 or more white balls in a sample of size 400 from an urn with 3000 white balls and 12000 black balls. Here are four ways to calculate it.

WebSep 11, 2024 · $\begingroup$ @FrankHarrell, I forgot to mention that I am working in the rare setting (MAF < 0.1%), with thousands of hypotheses (i.e. 2x2 tables) so it is quite likely I will get expected cell counts exactly zero. It is also my experience from simulations that the $\chi^2$ statistic is too liberal and does not always control the FDR (i.e. inflation). http://ceadserv1.nku.edu/longa//Rweb/library/base/html/Hypergeometric.html
