Quantile Function of the Generalized Normal Distribution

Description

This function computes the quantiles of the Generalized Normal (log-Normal) distribution given parameters (xi, α, and kappa) of the distribution computed by pargno. The quantile function of the distribution has no explicit form. The parameters have the following interpretations: xi is a location parameter, α is a scale parameter, and kappa is a shape parameter.

Usage

quagno(f, para)

Arguments

f Nonexceedance probability (0 <= F <= 1).
para The parameters from pargno or similar.

Value

Quantile value for nonexceedance probability F.
