qglg function

Quantile function for a generalized log-gamma distribution

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

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.

Returns

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

Examples

# Calculating the quartiles of a glg(0,1,-1) distribution
x <- c(0.25, 0.5, 0.75)
qglg(x, location = 0, scale = 1, shape = -1)
