Description: Penalized and nonlinear parametric modeling of quantile
        regression coefficient functions. The penalized integrated loss
        minimization estimator (lasso and group lasso penalties) of
        Sottile, Frumento, Chiodi and Bottai (2020)
        <doi:10.1177/1471082X19825523> performs covariate selection
        using the information on all quantiles simultaneously.
        Nonlinear parametric quantile models, in which the conditional
        quantile function can be a nonlinear function of the
        parameters, of the covariates or both, are estimated by
        integrated loss minimization as in Bottai and Cilluffo (2020)
        <doi:10.1177/0962280220941159>. Both approaches extend the
        quantile regression coefficients modeling framework of Frumento
        and Bottai (2016) <doi:10.1111/biom.12410> implemented in
        'qrcm'.
