+ "Estimation and Use of the Generalised (Tukey) Lambda Distribution")
+ (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.")
