# condSURV:
Estimation of the Conditional Survival Function for Ordered Multivariate
Failure Time Data

`condSURV`

is an R package to implement some newly
developed methods for the estimation of the conditional survival
function. The package implements three nonparametric and semiparametric
estimators for these quantities. The package also implements feasible
estimation methods for these quantities conditionally on current or past
covariate measures.

Other related estimators are also implemented in the package. One of
these estimators is the Kaplan-Meier estimator typically assumed to
estimate the survival function. A modification of the Kaplan-Meier
estimator, based on a preliminary estimation (presmoothing) of the
censoring probability for the survival time, given the available
information is also implemented.
