qmixt: Quantile function of mixture model.

Description

Computes qf of the mixture model.

Usage

qmixt(p, phi, spec1, arg1, spec2, arg2, interval = c(0, 100),
      lower.tail = TRUE, log.p = FALSE)

Arguments

p

scalar or vector of probabilities to compute the qf.

phi

the value of \(\phi\) parameter, \(\phi>0\).

spec1

a character string specifying the first parent distribution (for example, "lnorm" if the parent distribution corresponds to the lognormal).

arg1

list of arguments/parameters of the first parent distribution.

spec2

a character string specifying the second parent distribution (for example, "exp" if the parent distribution corresponds to the exponential).

arg2

list of arguments/parameters of the second parent distribution.

interval

a vector of interval end-points for p to search for the function root.

lower.tail

logical; if TRUE, probabilities are p, otherwise 1-p.

log.p

logical; if TRUE, probabilities p are returned as log(p).

Value

An object of the same length as p, giving the qf values computed at p.
