event2 {frailtypack}

Identify event2 indicator

Description

This is a special function used in the context of multivariate frailty model with two types of recurrent events and a terminal event (e.g., censoring variable related to both recurrent events). It contains the indicator of the recurrent event of type 2, normally 0=no event, 1=event, and is used on the right hand side of a formula of a 'multivPenal' object. Using event2() in a formula implies that a multivariate frailty model for two types of recurrent events and a terminal event is fitted.

Usage

event2(x)

Arguments

x

A numeric variable but should be a boolean which equals 1 if the subject has experienced an event of type 2 and 0 if not.
