Triangular Quantile Function

Share:

Description

Symmetric triangular density with endpoints equal to min and max.

Usage

1
 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.
