Usage

get_trans_intervals(gd, tmat)

Arguments

gd	A data.frame with the following named columns id: Subject idenitifier; state: State at which the subject is observed at time; time: Time at which the subject is observed; The true transition time between states is then interval censored between the times.
tmat	A transition matrix as created by transMat

Value

A data.frame with the following named columns

entry_time:

Time of entry into "from" state;

time_from:

Last time subject(id) was seen in state "from";

time_to:

First time subject(id) was seen in state "to";

from:

State from which a transition was observed;

to:

State to which the transition was observed;

id:

Subject identifier;

For right-censored observations, entry_time denotes the first time seen in the censored state, time_from the last time seen in the censored state, time_to is Inf, from the censored state and to is NA.
