In longevity: Statistical Methods for the Analysis of Excess Lifetimes

Beard distribution

Description

Distribution function, density, hazard, quantile function and random number generation for the Beard distribution

Usage

rbeard(n, rate, shape1, shape2)

pbeard(q, rate = 1, shape1 = 1, shape2 = 1, lower.tail = TRUE, log.p = FALSE)

dbeard(x, rate = 1, shape1 = 1, shape2 = 1, log = FALSE)

hbeard(x, rate = 1, shape1 = 1, shape2 = 1, log = FALSE)

qbeard(p, rate = 1, shape1 = 1, shape2 = 1, lower.tail = TRUE)

Arguments

n	sample size
rate	rate parameter (\nu)
shape1	shape parameter (\alpha)
shape2	shape parameter (\beta)
q	vector of quantiles.
lower.tail	logical; if TRUE (default), the lower tail probability \Pr(X \leq x) is returned.
log.p	logical; if FALSE (default), values are returned on the probability scale.
x	vector of quantiles.
log	logical; if FALSE (default), return the hazard
p	vector of probabilities.

Value

a vector of random variates

a vector of (log)-probabilities of the same length as q

a vector of (log)-density.

a vector of (log)-hazard.

a vector of quantiles
