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.") + (license license:gpl2+))) |
