%description
Quantile-based estimators (Q-estimators) fit any parametric distribution
through its quantile function, by minimizing the integrated loss of
quantile regression. They are usually more robust than maximum likelihood
estimators, and allow for censored and truncated data. The package
implements user-defined quantile functions, built-in families (normal,
gamma, continuous Poisson, uniform), linear models and proportional
hazards models. The method is described in Sottile and Frumento (2022)
<doi:10.1016/j.csda.2022.107471>.
