Beta prime distribution
Description
Density, distribution function, quantile function and random generation for the beta prime distribution.
Usage
dbetapr(x, shape1, shape2, scale = 1, log = FALSE)
pbetapr(q, shape1, shape2, scale = 1, lower.tail = TRUE, log.p = FALSE)
qbetapr(p, shape1, shape2, scale = 1, lower.tail = TRUE, log.p = FALSE)
rbetapr(n, shape1, shape2, scale = 1)
Arguments
