abstract: 'Diagnostics for linear L1 regression (also known as LAD - Least Absolute
  Deviations), including: estimation, confidence intervals, tests of hypotheses, measures
  of leverage, methods of diagnostics for L1 regression, special diagnostics graphs
  and measures of leverage. The algorithms are based in Dielman (2005) <https://doi.org/10.1080/0094965042000223680>,
  Elian et al. (2000) <https://doi.org/10.1080/03610920008832518> and Dodge (1997)
  <https://doi.org/10.1006/jmva.1997.1666>. This package builds on the ''quantreg''
  package, which is a well-established package for tuning quantile regression models.
  There are also tests to verify if the errors have a Laplace distribution based on
  the work of Puig and Stephens (2000) <https://doi.org/10.2307/1270952>.'
