Identify terminal indicator

Description

This is a special function used in the context of recurrent event models with terminal event (e.g., censoring variable related to recurrent events). It contains the status indicator, normally 0=alive, 1=dead, and is used on the right hand side of a formula of a 'frailtyPenal', 'longiPenal' and 'trivPenal' functions. Using terminal() in a formula implies that a joint frailty model for recurrent events and terminal events is fitted.

Usage

terminal(x)

Arguments

x	A numeric variable but should be a Boolean which equals 1 if the subject is dead and 0 if he is alive or censored, as a death indicator.
