get.surv.km: Calculate a survival probability at a given time by the standard Kaplan-Meier estimator.

Description

This function estimates \(Pr\{T > t_0\}\) by the Kaplan-Meier estimator. \(t_0\) should be given.

Usage

get.surv.km(time, event, t0, subs = NULL)

Arguments

time

Vector of follow up times.

event

Vector of event indicators, 1 for event of interest, 0 for censoring.

t0

Scalar value indicating a time to determine evnet/non-event (\(t_0\)).

subs

Vector of logical values to determine which subjects to be used for a calculation. When this option is not specified (subs = NULL), all subjects are used for a calculation.
