|---|---|
| direct | Direct |
| approxBinomial | Approximates hypergeometric distribution with binomial distribution. |
| approxPoisson | Approximates hypergeometric distribution with poisson distribution (uses gamma approximation, except for inverse CDF). |

| approxNormalContinuityCorrection | Approximates hypergeometric distribution with normal distribution (including continuity correction). |
Algorithms used to calculate hypergeometric distribution.
HypergeometricAlgo.direct can be more time-consuming for large values of the parameters. Additional algorithms are provided to the user to choose the trade-off between running time and accuracy.
