qtriang: Triangular Quantile Function

Description

Symmetric triangular density with endpoints equal to min and max.

Usage

qtriang(p, min = 0, max = 1)

Arguments

p

Vector of probabilities.

min

Left endpoint of the triangular distribution.

max

Right endpoint of the triangular distribution.

Value

qtriang gives the quantile function.

Details

The triangular distribution has density \(4 (x-a) / (b-a)^2\) for \(a \le x \le \mu\), and \(4 (b-x) / (b-a)^2\) for \(\mu < x \le b\), where \(a\) and \(b\) are the endpoints, and the mean of the distribution is \(\mu = (a+b) / 2\).
