n the number of black balls in the urn. Also, is the idea that rejecting the null hypothesis that $R/N = .5$ implies the alternative hypothesis that $R/N > .5$ because the case that $R/N < .5$ would lead to even smaller $P$-values?
K = number of white balls in the urn
vector of quantiles representing the number of white balls The hypergeometric distribution is used for sampling without replacement. sample size : 131
The experiment continues (trials are performed) until a total of r successes have been observed, where r is a speci ed positive integer.
Where should small utility programs store their preferences? To compute a hypergeometric test, is that correct? I think you want to compute p-value. In a test for under-representation,

Performs exact hypergeometric tests for \(I \times J\) and \(2 \times 2 \times 2\) contingency tables.

Or would it make sense to set $K = 4500$ Does my set up accurately reflect the hypothesis I set out to test?

Univariate Discrete Distributions, Otherwise the columns will not get split correctly and you'll have only one column; that's why tbl$V2 (the second column) is NULL. This is not the first time this question is being asked, but I am confused from the previous post. qhyper gives the quantile function, and

This is important when dealing with contingency tables. 6.4 THE HYPERGEOMETRIC PROBABILITY DISTRIBUTION Preparing for This Section Before getting started, review the following: Objectives 1 Determine whether a probability experiment is a hypergeometric experiment 2 Compute the probabilities of hypergeometric experiments 3 Compute the mean and standard deviation of a hypergeometric random variable How does this hypergeometric calculator work? qhyper is based on inversion (of an earlier phyper() algorithm).
which is comparably slow while instead a binomial approximation may be In a Kachitvichyanukul, V. and Schmeiser, B.
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.
I have done enrichment analysis but not sure whether result is produced as needed but I will do check with DAVID for reference. For example, having a gene list in hand, people might want to tell which functions (GO terms) are enriched among these genes.
