%description
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) <doi:10.1080/0094965042000223680>,
Elian et al. (2000) <doi:10.1080/03610920008832518> and Dodge (1997)
<doi: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)
<doi:10.2307/1270952>.
