L-moments of the Weibull Distribution

Description

This function estimates the L-moments of the Weibull distribution given the parameters (zeta, β, and delta) from parwei. The Weibull distribution is a reverse Generalized Extreme Value distribution. As result, the Generalized Extreme Value algorithms (lmomgev) are used for computation of the L-moments of the Weibull in this package (see parwei).

Usage

lmomwei(para)

Arguments

para The parameters of the distribution.

Value

An R list is returned.

L1 Arithmetic mean.
L2 L-scale—analogous to standard deviation.
LCV coefficient of L-variation—analogous to coefficient of variation.
TAU3 The third L-moment ratio or L-skew—analogous to skew.
TAU4 The fourth L-moment ratio or L-kurtosis—analogous to kurtosis.
TAU5 The fifth L-moment ratio.
L3 The third L-moment.
L4 The fourth L-moment.
L5 The fifth L-moment.
source An attribute identifying the computational source of the L-moments: “lmomwei”.
