%description
Random Hazard Forests (RHF) extend Random Survival Forests (RSF) by
directly estimating the hazard function and by accommodating
time-dependent covariates through counting-process style inputs. The
package fits tree ensembles for dynamic survival prediction, returning
hazard, cumulative hazard, integrated hazard, and related performance
summaries for training and test data. The methods build on Random Survival
Forests described by Ishwaran et al. (2008) <doi:10.1214/08-AOAS169> and
on nonparametric hazard modeling with time-dependent covariates described
by Lee et al. (2021) <doi:10.1214/20-AOS2028>.
