x, q |
vector of quantiles. |
shape1, shape2 |
non-negative parameters. |
scale |
positive valued scale parameter. |
log, log.p |
logical; if TRUE, probabilities p are given as log(p). |
lower.tail |
logical; if TRUE (default), probabilities are P[X ≤ x] otherwise, P[X > x]. |
p |
vector of probabilities. |
n |
number of observations. If |
If X ~ Beta(α, β), then X/(1-X) ~ BetaPrime(α, β).
Probability density function
f(x) = ((x/σ)^(α-1) * (1 + x/σ)^(-α-β)) / (B(α,β) * σ)
Cumulative distribution function
F(x) = pbeta((x/σ)/(1+(x/σ)), α, β)
