In LambertW: Probabilistic Models to Analyze and Gaussianize Heavy-Tailed, Skewed Data

LambertW R package

This is the github repo for the LambertW R package hosted on CRAN. For any changes after the official version, see the commit history and here.

Installation & usage

To install LambertW run

install.packages("LambertW")
citation("LambertW")

See ?LambertW for examples on how to use the LambertW package.

There is also an R vignette on CRAN with a brief tutorial on the main functionalities.

Python implementation

See https://github.com/gmgeorg/pylambertw for the Python equivalent of the LambertW package.

Tutorials & posts

See cross-validated / stackoverflow for a variety of LambertW posts on how to normalize/Gaussianize data and model skewed/heavy-tailed distributions.
