Hypergeometric Distribution-based Hypothesis Testing
hyperg_test(term_genes, chosen_genes, background_genes)
term_genes |
vector of genes in the selected term gene set |
chosen_genes |
vector containing the set of input genes |
background_genes |
vector of background genes (i.e. universal set of genes in the experiment) |
To determine whether the chosen_genes
are enriched
(compared to a background pool of genes) in the term_genes
, the
hypergeometric distribution is assumed and the appropriate p value
(the value under the right tail) is calculated and returned.
the p-value as determined using the hypergeometric distribution.
