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. WebPrincipales diferencias entre las funciones dhyper, phyper, qhyper y rhyper. En estadística, las funciones hipergeométricas se utilizan para calcular la probabilidad de que un determinado número de éxitos ocurra en una muestra de tamaño fijo, cuando se selecciona al azar de una población de tamaño fijo.

WebFor example, phyper(59, 150, 150, 60, FALSE, FALSE) gives 6.372680161e-14. The right answer is dhyper(0, 150, 150, 60, FALSE) which is 5.111204798e-22. phyper is also really slow for large arguments. Therefore, I suggest using the code below.
