rSurv_conditional_fun {nph}

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

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.

Value

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