qglg {sglg}

Quantile function for a generalized log-gamma distribution

Description

qglg is used to calculate the quantile function of a generalized log-gamma variable at x.

Usage

qglg(x, location, scale, shape)

Arguments

x

numeric, a vector with values between 0 and 1.

location

numeric, represents the location parameter of a generalized log-gamma distribution. Default value is 0.

scale

numeric, represents the scale parameter of a generalized log-gamma distribution. Default value is 1.

shape

numeric, represents the shape parameter of a generalized log-gamma distribution. Default value is 1.

Value

A vector with the same size of x with the quantile values of a generalized log-gamma distribution.
