qtailw {distTails}

Quantile function

Description

This function computes the quantile function of the tailW.

Q(p,\alpha, \beta, \nu) = \left(\frac{-\log(1 - p)}{\alpha} + \nu^\beta\right)^{1 / \beta}

Usage

qtailw(p, threshold, scale, shape)

Arguments

p

Probability.

threshold

Minimum value of the tail.

scale

Scale parameter.

shape

Shape parameter.

Value

Gives the quantiles of the TailW. The length of the result is determined by the length of x.

Examples

qtailw(0.5, 1, 1, 1)
