Release 1.0.0 of the new R package 'randomSurvivalForest' is now available
on CRAN and its mirrors. The package implements Ishwaran and Kogalur's
Random Survival Forests algorithm for right censored survival data. The
algorithm is closely patterned after Breiman's random forests, but suitably
modified for the survival setting. Some key features are:
o An ensemble cumulative hazard is constructed
from binary recursive survival trees grown
under different splitting rules.
o Mortality estimates interpretable in terms
of total number of deaths are provided.
o An out-of-bag estimate of Harrell's concordance
index is provided for assessing prediction.
Detailed information on usage can be found in the manual.
