absTd: Absolute Student t Distribution.

Description

Density, distribution function and quantile function of the absolute t distribution.

Usage

d.absTd(x, df, ncp = 0, ...)
p.absTd(q, df, ncp = 0, lower.tail = FALSE, ...)
q.absTd(p, df, ncp = 0, lower.tail = FALSE, ...)

Arguments

x,q

vector of quantiles.

p

vector of probabilities.

df

degrees of freedom (>0).

ncp

noncentrality parameter.

lower.tail

logical, if lower.tail=FALSE, probabilities are $P[X > x]$, otherwise, $P[X \leq x]$.

...

arguments to pass to functions d, p or q in R package distr.

Value

numeric of length equal to the length of x.

Details

Based on R package distr.
