Usage

prepare.los.data(x) 

Arguments

x data.frame of the form data.frame(id, j.01, j.02, j.03, j.12, j.13, cens):
id:
id (patient id, admision id)
j.01:
observed time for jump from 0 to 1
j.02:
observed time for jump from 0 to 2
j.03:
observed time for jump from 0 to 3
j.12:
observed time for jump from 1 to 2
j.13:
observed time for jump from 1 to 3
cens:
censoring time (either in initial or intermediate state)

Value

a data.frame of the form data.frame(id, from, to, time, oid):

id: id (patient id, admision id)
from: the state from where a transition occurs
to: the state to which a transition occurs
time: time of the transition
oid: the observation id

Note

For bootstrap applications (see the examples to clos), where an individual may enter the new bootstrap data set several times, it is useful to have 'oid', which will tell several draws of the same individual apart.
