fun.lm.theo.gld {GLDEX}

Find the theoretical first four L moments of the generalised lambda distribution.

Description

This function computes the first four L moments for both RS and FMKL generalised lambda distributions.

Usage

fun.lm.theo.gld(L1, L2, L3, L4, param)

Arguments

L1

Lambda 1. Or c(Lambda 1,Lambda 2,Lambda 3,Lambda 4).

L2

Lambda 2.

L3

Lambda 3.

L4

Lambda 4.

param

"rs" or "fmkl" or "fkml"

Value

A vector listing the first four L moments

Note

Sometimes the theoretical moments may not exist, in those cases, NA is returned.
