In mHG: Minimum-Hypergeometric Test

Description Usage Arguments Details Value Author(s) References Examples

Calculates the p-value associated with the (minimum-hypergeometric) mHG statistic.

1	mHG.pval.calc(p, N, B, n_max = N)

`p`	the mHG statistic. It is marked as p as it represents an "uncorrected" p-value.
`N`	total number of white and black balls (according to the hypergeometric problem definition).
`B`	number of black balls.
`n_max`	the algorithm will calculate the p-value under the assumption that only the first n_max partitions were taken into account in determining the mHG statistic.

O(NB) running time, O(NB) space.

the p-value of the test.
