iCoxBoost
(Package: CoxBoost) :
Interface for cross-validation and model fitting using a formula description
Formula interface for fitting a Cox proportional hazards model by componentwise likelihood based boosting (via a call to CoxBoost), where cross-validation can be performed automatically for determining the number of boosting steps (via a call to cv.CoxBoost).
