lss: Measures of location, scale and shape measures for a generalized log-gamma distribution

Description

lss is used to obtain the mean, median, mode, variance, coefficient of variation, skewness and kurtosis for a generalized log-gamma distribution.

Usage

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

lss(0,1,-1)    # Extreme value type I distribution, maximum case.
lss(0,1,1)     # Extreme value type I distribution, minimum case.
lss(0,1,0.01) # Standard normal distribution.
