%description
Smooth additive quantile regression models, fitted using the methods of
Fasiolo et al. (2020) <doi:10.1080/01621459.2020.1725521>. See Fasiolo at
al. (2021) <doi:10.18637/jss.v100.i09> for an introduction to the package.
Differently from 'quantreg', the smoothing parameters are estimated
automatically by marginal loss minimization, while the regression
coefficients are estimated using either PIRLS or Newton algorithm. The
learning rate is determined so that the Bayesian credible intervals of the
estimated effects have approximately the correct coverage. The main
function is qgam() which is similar to gam() in 'mgcv', but fits
non-parametric quantile regression models.
