In GLDEX: Fitting Single and Mixture of Generalised Lambda Distributions

Fit FMKL generalised lambda distribution to data set using maximum likelihood estimation

Description

This function fits FMKL generalised lambda distribution to data set using maximum likelihood estimation.

Usage

fun.RMFMKL.ml(data, fmkl.init = c(-0.25, 1.5), leap = 3,FUN="runif.sobol",
no=10000)

Arguments

data	Dataset to be fitted
fmkl.init	Initial values for FMKL distribution optimization, c(-0.25,1.5) tends to work well.
leap	See scrambling argument in fun.gen.qrn.
FUN	A character string of either "runif.sobol" (default), "runif.sobol.owen", "runif.halton" or "QUnif".
no	Number of initial random values to find the best initial values for optimisation.

Details

This function provides one of the definitive fit to data set using generalised lambda distributions.

Value

A vector representing four parameters of the FMKL generalised lambda distribution.
