phyperBin {DPQ} | R Documentation |
Compute hypergeometric cumulative probabilities via (good) binomial
distribution approximations.
The arguments of these functions are exactly those of R's own
phyper()

phyperBin.1(q, m, n, k, lower.tail = TRUE, log.p = FALSE) phyperBin.2(q, m, n, k, lower.tail = TRUE, log.p = FALSE) phyperBin.3(q, m, n, k, lower.tail = TRUE, log.p = FALSE) phyperBin.4(q, m, n, k, lower.tail = TRUE, log.p = FALSE)
q |
vector of quantiles representing the number of white balls drawn without replacement from an urn which contains both black and white balls. |
m |
the number of white balls in the urn. |
n |
the number of black balls in the urn. |
k |
the number of balls drawn from the urn, hence must be in 0,1,…, m+n. |
lower.tail |
logical; if TRUE (default), probabilities are P[X ≤ x], otherwise, P[X > x]. |
log.p |
logical; if TRUE, probabilities p are given as log(p). |

## The function is simply defined as function (q, m, n, k, lower.tail = TRUE, log.p = FALSE) pbinom(q, size = k, prob = m/(m + n), lower.tail = lower.tail, log.p = log.p)
