rSurv_conditional_fun: Draw conditional random survival times from mixpch object.

Description

Draws independent random survival times from mixpch objects conditional on observed time.

Usage

rSurv_conditional_fun(x, y)

Arguments

x

An object of class mixpch

y

A vector of observed right censored times

Value

A vector of random survival times, conditional on the observed censored times.

Details

Note that the mixpch object stores the survival function up to some time T. For random times equal or larger T, the value T is returned.
