Description: The generalised lambda distribution, or Tukey lambda distribution,
provides a wide variety of shapes with one functional form.
This package provides random numbers, quantiles, probabilities,
densities and density quantiles for four different types of the distribution,
the FKML (Freimer et al 1988), RS (Ramberg and Schmeiser 1974), GPD (van Staden
and Loots 2009) and FM5 - see documentation for details.
It provides the density function, distribution function, and Quantile-Quantile
plots.
It implements a variety of estimation methods for the distribution,
including diagnostic plots.
Estimation methods include the starship (all 4 types),
method of L-Moments for the GPD and FKML types, and a
number of methods for only the FKML type.
These include maximum likelihood, maximum product of spacings,
Titterington's method, Moments, Trimmed L-Moments and Distributional Least Absolutes.

Description: The generalized lambda distribution (GLD) is a versatile
distribution that can accommodate a wide range of shapes,
including fat-tailed and asymmetric distributions. This package
implements a more intuitive parameterization of the GLD that
expresses the location and scale parameters directly as the
median and inter-quartile range of the distribution. The
remaining two shape parameters characterize the asymmetry and
steepness of the distribution respectively. The fitting of the
GLD to empirical data can be reduced to a two-parameter
estimation problem where the location and scale parameters are
estimated by their robust sample estimators. Moreover, the
parameterization can be used to compare data sets in a
convenient asymmetry and steepness shape plot. The underline C
routines are written such that compilers that support
vectorized mathematical operations can automatically vectorize
the most time consuming loops (tested with icc 12.1.0). The
package includes the usual distribution functions, fitting
routines and a shape plot function.
