The survPresmooth package for R implements nonparametric presmoothed estimators of the main functions studied in survival analysis (survival, density, hazard and cumulative hazard functions). Presmoothed versions of the classical nonparametric estimators have been shown to increase efficiency if the presmoothing bandwidth is suitably chosen. The survPresmooth package provides plug-in and bootstrap bandwidth selectors, also allowing the possibility of using fixed bandwidths.
