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.
