moors_lss: Measures of location, scale, and shape based on quantile measures for a generalized log-gamma distribution

Description

moors_lss is used to obtain the median, the half interquartile range and the quantile coefficient of skewness and kurtosis for a generalized log-gamma distribution.

Usage

moors_lss(mu = 0, sigma = 1, lambda = 1)

Arguments

mu

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

sigma

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

lambda

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

Examples

moors_lss(mu = 0,sigma = 1,lambda = -1)    # Extreme value type I distribution, maximum case.
moors_lss(mu = 0,sigma = 1,lambda = 1)     # Extreme value type I distribution, minimum case.
moors_lss(mu = 0,sigma = 1,lambda = 0.05) # Standard normal distribution.
