%description
Density, distribution function, quantile function, and random generation
function, maximum likelihood estimation (MLE), penalized maximum
likelihood estimation (PMLE), the quartiles method estimation (QM), and
median rank estimation (MEDRANK) for the two-parameter exponential
distribution. MLE and PMLE are based on Mengjie Zheng
(2013)<https://scse.d.umn.edu/sites/scse.d.umn.edu/files/mengjie-thesis_masters-1.pdf>.
QM is based on Entisar Elgmati and Nadia Gregni
(2016)<doi:10.5539/ijsp.v5n5p12>. MEDRANK is based on Matthew Reid
(2022)<doi:10.5281/ZENODO.3938000>.
