%description
Fit a predictive model using iteratively reweighted boosting (IRBoost) to
minimize robust loss functions within the CC-family (concave-convex). This
constitutes an application of iteratively reweighted convex optimization
(IRCO), where convex optimization is performed using the functional
descent boosting algorithm. IRBoost assigns weights to facilitate outlier
identification. Applications include robust generalized linear models and
robust accelerated failure time models. Wang (2021)
