qtriang: Triangular Quantile Function

In jmuOutlier: Permutation Tests for Nonparametric Statistics

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.

Details

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

Value

qtriang gives the quantile function.
