log-logistic distribution

Description

Density, distribution function, and quantile function for log-logistic distribution.

Usage

dllogis(x, locationlog = 0, scalelog = 1, log = FALSE)

pllogis(q, locationlog = 0, scalelog = 1, lower.tail = TRUE, log.p = FALSE)

qllogis(p, locationlog = 0, scalelog = 1, lower.tail = TRUE, log.p = FALSE)

rllogis(n, locationlog = 0, scalelog = 1)

Arguments

x, q	A numeric vector of quantiles.
locationlog	A numeric value of location parameter for the logistic distribution.
scalelog	A numeric value of scale parameter for the logistic distribution.
log, log.p	A logical; if TRUE, the probability p is given as log(p).
lower.tail	A logical; if TRUE, the probability is P[X <= x], otherwise, P[X > x].
p	A numeric vector of probabilities.

Details

The log-logistic distribution has the cumulative distribution function F(q) = G(log(q)) where G(q) is the cumulative distribution function of the logistic distribution with location and scale.

Value

'dllogis' gives the desity, 'pllogis' gives the distribution, and 'qllogis' gives the quantile function.
