Distribution function of the extended Weibull distribution

Description

Distribution function of the extended Weibull distribution

Density function of the extended Weibull distribution

Hazard function of the extended Weibull distribution

Quantile function of the extended Weibull distribution

Usage

pextweibull(
  q,
  scale = 1,
  shape1 = 0,
  shape2 = 1,
  lower.tail = TRUE,
  log.p = FALSE
)

dextweibull(x, scale = 1, shape1 = 0, shape2 = 1, log = FALSE)

hextweibull(x, scale = 1, shape1 = 0, shape2 = 1, log = FALSE)

qextweibull(p, scale = 1, shape1 = 0, shape2 = 1, lower.tail = TRUE)

Arguments

q	vector of quantiles.
scale	scale parameter, strictly positive.
shape1	shape parameter of the generalized Pareto component.
shape2	shape parameter of the Weibull component.
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, else the log hazard.
p	vector of probabilities.

Value

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

a vector of (log)-density.

a vector of (log)-hazard

vector of quantiles

a vector of quantiles
