LambertW: Analyze and Gaussianize heavy-tailed, skewed data

Lambert W x F distributions are a generalized framework to analyze skewed, heavy-tailed data. They are based on an input/output system, where the input random variable (RV) X ~ F, and the output Y is a non-linearly transformed version of X with similar properties, but slightly skewed and/or heavy-tailed. This transformed RV Y has a Lambert W x F distribution. This package contains functions to model and analyze skewed, heavy-tailed data the Lambert Way: simulate random samples, estimate parameters, compute quantiles, and plot/print results nicely. Probably the most important function is 'Gaussianize', which works similarly to 'scale', but actually makes the data Gaussian. A do-it-yourself toolkit allows users to define their own Lambert W x 'MyFavoriteDistribution' and use it in their analysis right away.
