L-moments {POT}

Compute Sample L-moments

Description

Compute the sample L-moments - unbiased version.

Usage

samlmu(x, nmom = 4, sort.data = TRUE)

Arguments

x

a vector of data

nmom

a numeric value giving the number of sample L-moments to be computed

sort.data

a logical which specifies if the vector of data x should be sorted or not.

Value

This function returns a vector of length nmom corresponding to the sample L-moments. Note that for orders greater or equal than 3 it is the L-moments ratio that is sample L-coefficient of variation, sample L-skewness, sample L-kurtosis, ...
